David Allan Howe is a research advisor to the Time and Frequency Division of the National Institute of Standards and Technology (NIST) and Colorado University Physics Department, Boulder, CO. His expertise includes time-series analysis, automated accuracy evaluation of primary cesium standards, reduction of oscillator acceleration sensitivity and precision spectral analysis. He worked with David Wineland from 1973 to 1987 doing advanced research on NIST’s primary cesium standard and compact hydrogen and ammonia standards. He developed and built the first operating compact hydrogen masers in 1979, led and implemented global high-accuracy satellite-based time-synchronization among national laboratories in the maintenance of Universal Coordinated Time (UTC).




Atomic clocks (or oscillators) form the basis of standard, everyday timekeeping. Separated, hi-accuracy clocks can maintain nanosecond-level autonomous synchronization for many days. The world’s best Cs time standards are atomic fountains that use convenient RF quantum transition at 9,192,631,770 Hz and reach total frequency uncertainties of 2.7–4×10-16 with many days of averaging time. A new class of optical atomic standards with quantum transitions having +1×10-15 uncertainties drives an optical frequency-comb divider (OFD), thus providing exceptional phase stability, or ultra-low phase noise (ULPN), at convenient RF frequencies. In terms of time, this means that a 1 ns time difference wouldn’t occur in a network of clocks for 15 days! I show how the combination of high atomic accuracy and low-phase noise coupled with reduced size, weight and power usage pushes certain limits of physics to unlock a new paradigm – creating networks of separated oscillators that maintain extended phase coherence, or a virtual lock, with no means of synchronization whatsoever except at the start. This single property elevates their usage to a vast array of applications that extend far beyond everyday timekeeping. I show how such accurate oscillators with low-phase noise dramatically improves: 1) position, navigation and timing; 2) high-speed communications, 3) private messaging and cryptology, 4) spectrum sharing, 5) relativity theory and 6) measurements of quantum consistency, i.e., alpha-dot. This talk outlines game-changing possibilities in these areas to the degree that clock properties are maintained in application and lab environments. I will show a summary of several ongoing U.S. programs in which the commercial availability of such low-phase noise, atomic oscillators are now a real possibility.

The fate of an ultra-short laser pulse propagating in air depends crucially upon its initial peak power. Below a critical value Pcr, group velocity dispersion and beam diffraction combine to rapidly reduce the pulse intensity. On the other hand, if P>Pcr a completely different behavior is observed. In this case the pulse intensity increases with distance up to the point where it becomes sufficiently high (≈1014 W/cm²) to ionize air. The pulse then retains this high intensity for very long distances, which can reach km. This regime is called filamentation. In this talk the basic notions at the heart of filamentation will be introduced. Techniques to characterize filaments will be described. This includes measurements of the beam size, pulse intensity and duration, length of the plasma column created in the wake of the pulse and the plasma density evolution. Results of numerical simulations reproducing the filamentary regime will be shown. A second part will be devoted to applications of filaments. They include the remote sensing of atmosphere, the triggering of long-lived electric discharges and the contactless transfer of high electric power and more recently the realization of cavity-free lasing in air.

He has participated in the international academic conferences over 40 times and he visited more than 20 countries. In 1994, he visited eight institutes in USA to give lectures. He is the first Chinese Astrophysicist to visit NASA and to give a lecture on the topic, “Nuclear Synthesis of Interstellar 26Al”. In 2005, he visited USA twice and gave lectures in eight universities again. Inviting six astronomers of USA to give series lectures, he has hosted four consecutive terms summer school on gravitational wave astronomy. After the four summer school obvious effect, at least 20 young scholars in China in the field of gravitational wave astronomy specialized learning and research. 220 research papers by him have been published.


A key observation has been reported in 2013: an abnormally strong radial magnetic field near the GC is discovered. Firstly, we demonstrate that the radiations observed from the GC are hardly emitted by the gas of accretion disk which is prevented from approaching to the GC by the abnormally strong radial magnetic field and these radiations can't be emitted by the black hole model at the Center. However, the dilemma of the black hole model at the GC be naturally solved in our model of super massive object with magnetic monopoles (MMs). Three predictions in our model are quantitatively in agreement with observations: 1) Plenty of positrons are produced from the direction of the GC with the rate is or so. This prediction is quantitatively confirmed by observation, 2) A strong radial magnetic field is generated by some magnetic monopoles condensed in the core region of the super massive object The magnetic field strength at the surface of the object is about 20-100 Gauss at 1.1×〖10^4 R_s (R_s is the Schwarzschild radius) or B≈(10-50) mG at r=0.12 pc. This prediction is quantitatively in agreement with the lower limit of the observed magnetic field and 3) The surface temperature of the super-massive object in the Galactic center is about 120 K and the corresponding spectrum peak of the thermal radiation is at 〖10^13[PC1]  Hz in the sub-mm wavelength regime. This is quantitatively basically consistent with the recent observation. It could be concluded that it could be an astronomical observational evidence of the existence of MMs and no black hole is at the GC. Besides, making use of both the estimations for the space flux of MMs and nucleon decay catalyzed by MMs (called the RC effect) to obtain the luminosity of celestial objects by the RC effect. In terms of the formula for this RC luminosity we are able to present a unified treatment for various kinds of core collapsed supernovae, SNII, SNIb, SNIc, SLSN (super luminous supernova) and the production mechanism for γ ray burst. The remnant of the supernova explosion is a neutron star rather than a black hole, regardless of the mass of the progenitor of the supernova. Besides, the heat source of the earth’s core as well as the energy source needed for the white dwarf interior is the same mechanism of the energy source as supernova. This unified model can also be used to reasonably explain the possible association of the shot γ ray burst detected by the Fermi γ ray Burst Monitoring Satellite (GBM) with the September 2015 LIGO gravitational wave event GW150914. Finally, we propose that the physical mechanism of Hot Big Bang of the Universe is also nucleons decay driven by the magnetic monopoles, similar to the supernova explosion.

We are facing the problem of possible future running out of oil parallel with increase of energy consumption in connection with the expected population growth to 8-10 billion people to the year of 2050. At the moment, we are emitting twice the amount of CO2 that atmosphere can integrate. For solving this issue, alternate energy sources are solar, wind, but also high-Tc superconductivity at hand. For instance, the electricity generation by photovoltaics (PV) is needed to highly expand over the present scale of Gigawatts. In connection with this goal, development of energy storage and transportation technologies will be necessary. Together with solving the energy production and transport issues, development of new materials and innovative technologies saving energy consumption is crucial. In this talk, recent trends in high-Tc superconducting material processing will be introduced and then the new super-magnet applications will be presented. The bulk superconducting magnets can trap magnetic fields by order of magnitude higher than the best classical hard magnets and are therefore promising as permanent magnets for use in magnetic drug delivery system (MDDS), for construction of small mobile diagnostic devices, for water cleaning technologies, etc. Human’s body is so complicated that a controlled drug delivery is extremely difficult. This process can be accomplished by magnetic force in the body by exerting a strong magnetic field on the diseased tissue. As a result, a high drug concentration can be delivered in a controlled way to the targeted diseased organ. Superconducting material is also used in superconducting DC cables, promising in particular in transport of solar energy as well as in feeding cables for railway system applications. In this presentation, I will summarize the recent development in use of bulk superconducting materials in superconducting magnets and of superconducting cables in various industrial applications.

Title: Route to understand non-ergodic quantum systems

Time : 16:10- 17:10


Prof P. Singha Deo did his PhD in 1996 and has remained associated with research and teaching in physics in premier institutions and universities abroad and in India. He has published more than 50 papers in international journals. He is a professor at S.N. Bose Centre, Kolkata since 1999 and successfully guided several PhD thesis. He has worked on various issues and problems in mesoscopic physics and correlated systems. Some of his current research topics include quantum devices, quantum capacitance, bosonization in higher dimensions, quantum mechanical scattering phase shift in low dimensions, etc.



Small quantum systems are non-ergodic. Electrons transmitted through a scatterer (region shaded blue) does not access all the states of the scatterer and we do not have the liberty to take an ensemble average or average over impurity configuration. In most transport measurements it is the partial density of states (pdos) that play a relevant role while it is never possible to know exact impurity configuration or the confinement potential that determines it. The pdos also crucially depends on the positions and nature of the leads (marked L and R) and so it is not enough to know the hamiltonian of the system or the partition function. Besides the leads that determine the asymptotic states in the scattering process always have free electron states while many body effects are inevitable inside the scatterer. How a free electron is transmitted through an interacting environment is a formidable theoretical problem as it requires matching a one body wavefunction to a many body wavefunction.We prove that pdos can be determined experimentally from the asymptotic free electron states at the resonances and sometimes it can be negative. There can be large errors in the non-resonant regime but non-resonant pdos is so small in magnitude that they may be ignored. Since our analysis is general, our results are valid for transmission through an interacting environment. From the pdos we can determine all other relevant quantities that can be probed by an experiment and thus we provide a novel and new technique to understand non-ergodic quantum systems. Negative pdos can also give rise to electron-electron attraction and also throws some light on the nature of traversal times. We consider several typical scattering potentials to demonstrate our results. We believe that our results can lead to the development on new technologies.

Session Introduction

Alessandra Toncelli

University of Pisa, Italy

Title: MID-IR spectroscopy of Nd3+ and Ce3+ ions in crystals

Time : 14:50-15:20


Alessandra Toncelli has obtained her PhD in Physics in 1998 at the University of Pisa. Since 2017 she is Associate Professor at the Physics Department of Pisa. Her scientific interest was initially aimed to the growth and spectroscopy of crystalline materials for photonic applications in visible and near infrared regions. In particular, she studied and characterized the optical and spectroscopic properties of oxide and fluoride crystals with rare earths for laser applications. She has published more than 160 articles on International journals. She currently holds an h-index of 41 both in Scopus and in ISI web of knowledge.



The mid-infrared (MID-IR) region is very interesting for a large number of applications because vibro-rotational levels of many molecules lie in this region. Therefore, the search for new light sources in this range is a very important research topic. Moreover, MID-IR energy levels of rare earth ions in crystals are usually the bottom laser levels for visible or near infrared lasers based on these materials. For these reasons, we performed MID-IR spectroscopy of the Nd3+-Ce3+:YAG system. Ce3+ ions are added as sensitizers for Nd3+ because Ce3+ possesses a strong absorption band at around 450 nm where powerful diode lasers exist. The efficient energy transfer mechanism at visible energy that transfers the Ce excitation to the upper Nd laser level has already been studied, but, at the best of our knowledge, no detailed investigation has been performed about the possible interaction between the MID-IR energy levels of the two ions. This might play an important role in the laser efficiency because of the possible energy match with the bottom laser level of the near-infrared Nd emission. Absorption spectra of Nd:YAG, Ce:YAG and Nd,Ce:YAG have been performed as a function of temperature in the 7000-1000 cm-1 wavenumber range to identify the transparency limit of the crystal matrix and the MID-IR energy levels of the two ions. Ce:2F7/2 together with Nd: 4I15/2, 4I13/2 and 4I11/2 Stark sublevels have been observed and identified. Good spectral overlap has been observed between the Ce:2F7/2 Stark components and Nd: 4I13/2, and 4I11/2 multiplets. This might help in depopulating the lower laser level of the 1.06 mm and 1.3 mm laser emission of Nd thus favoring the laser emission at these wavelengths. Moreover, the 4.8-5 mm Nd emission has been observed and characterized at room temperature.

Title: Motley String or from 10 to 4

Time : 15:20-15:50

He has joined as Junior Researcher in Ioffe Physical Technical Institute of Academy of Sciences of USSR, Department of Plasma Physics and Astrophysics, where he did research of ion-acoustic waves in plasma.

All known String models (Bosonic, Super string, Heterotic) are formulated in multi-dimensional space time. To get to realistic and observable 4-dimensional world requires new type of theory. To avoid all inconsistencies present in known approaches to compactification we propose Motley string model, which treats all special dimensions equally and complies with known experimental material. First we formulate two postulates: (1) Every special dimension of string has unique intrinsic property which we call color and (2) there is force between special dimensions of string such that it makes dimensions of complementary colors (Redi, Greeni, Bluei) interact and unite in a colorless threads perceived as observable dimensions. Color property of string’s special dimensions is somewhat similar to 3 color charges of quarks in Quantum Chromo Dynamics, but has different meaning, since it is viewed here as intrinsic characteristic of special dimensions in Motley String theory corresponding to different values of string tension tensor Ti in different dimensions. String state at very high energies (early universe, Planck length about 10-33 cm) is such that all string special dimensions are in a free state similar to quark-gluon plasma of Quantum Chromo Dynamics. At lower energies (modern universe) strong color force becomes dominant and makes String’s complimentary (or using classical optics term additive) special dimensions (Redi, Greeni, Bluei) interact to form 3 threads (in case of 9+1 dimensional superstring) which appear to be colorless from distances larger than size of baryons (proton and neutron). Special dimensions of additive colors are glued together. Outside of Planck energy scale special dimensions are confined in colorless 3-dimensional threads. Since in our model all special dimensions are treated uniformly we avoid questions like: Why some special dimensions are compactified while others are not? Also there are no standing waves in curved dimensions of Klein compactification and therefore no extra mass values (Kaluza-Klein tower). Equally important there is no need for Calabi-Yau and somewhat artificial large extra dimensions models invented to explain unseen special dimensions. Motley String theory and idea of colorful special dimensions introduced in this article offers consistent and uniform approach to compactification problem present in all string models (Superstring, Bosonic, Heterotic). It eliminates inconsistencies of compactification mechanisms proposed earlier (Kaluza-Klein, Calabi-Yau manifolds, etc.). Also it solves several major problems present in the Standard Model and Cosmology like; explains number of particle generations (6 quarks and 6 leptons) of standard model and quark/gluon confinement, explains fractional charges of quarks, establishes the link between multi-dimensional string theories and observable 4-dimensional world, offers alternative to Higgs mechanism for particles mass generation and thus explains neutrino's mass and experimentally observed neutrino oscillations, and offers solution for dark matter/energy problem of modern astrophysics.
