Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global strong solutions to the two-dimensional radially symmetric compressible MHD
二维径向对称 可压缩 磁流体动力学 全局强解
2023/12/11
In this talk, I will present our recent result the 2D radially symmetric compressible MHD with density-dependent viscosity. Under the condition of beta>1, we prove the global existence of the radially...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Many-body localization and quantum many-body scars: The strong and weak form of ergodicity breaking
多体定位 量子多体疤痕 遍历性断裂 强弱形式
2023/4/23
The fate of an isolated quantum many-body system has attracted much attention in the past decade. One of the most important issues is whether such a system can reach thermalization under its own dynam...
Low frequency signal spectrum analysis for strong earthquakes
VLF/LF signal propagation eartquake precursors
2015/8/24
We examined changes in the spectral composition of the low frequency (LF) subionospheric signals from the NRK transmitter (37.5 kHz) in Iceland that were received in Bari (Italy) relative to the earth...
Unconventional Rotational Responses of Hadronic Superfluids in a Neutron Star Caused by Strong Entrainment and a Σ- Hyperon Gap
Neutron star spinning reaction model whirlpool proton vortex a charged condenser coil
2014/12/19
I show that the usual model of the rotational response of a neutron star, which predicts rotation-induced neutronic vortices and no rotation-induced protonic vortices, does not hold (i) beyond a certa...
Demonstration of Strong Near-Field Radiative Heat Transfer between Integrated Nanostructures
Thermal transport thermal radiation near-fi eld radiation microelectromechanical systems (MEMS) surface phonon-polariton
2015/8/6
Near-field heat transfer recently attracted growing interest but was demonstrated experimentally only in macroscopic systems. However, several projected applications would be relevant mostly in ...
Simulation of Pair Production in Extreme Strong EM Fields
Schwinger-mechanism pair production space-time dependent fields
2012/5/29
In this article we review a theoretical framework for pair production from strong external electromagnetic fields. We propose a numerical method to solve the resulting equations of motion and present ...
Quasiclassical approach to high-energy QED processes in strong laser and atomic fields

2012/4/20
An approach, based on the use of the quasiclassical Green's function, is developed for investigating high-energy quantum electrodynamical processes in combined strong laser and atomic fields. Employin...

2011/9/9
Radiative polarization of electrons brought into collision with a high power laser is studied. We derive an expression for the squared amplitude of this process (summed over polarizations of the final...

The scalar mesons $\sigma(600)$, $\kappa(800)$, $f_0(980)$ and $a_0(980)$ together with the pseudo Goldstone bosons $\pi$, $K$, and $\eta$ may be considered as the Higgs sector of strong interaction.
Ultra-strong laser pulses: streak-camera for gamma-rays via pair production and quantum radiative reaction

Abstract: We show that a strong laser pulse combined with a strong x-ray pulse can be employed in a detection scheme for characterizing high-energy $\gamma$-ray pulses down to the zeptosecond timescal...
Nuclear collision in strong magnetic field
Nuclear collision strong magnetic field isospin physics
2011/7/20
We studied nucleus-nucleus collision in strong magnetic field based on a transport model. It is found that neutrons and protons can be separated from a nucleus by strong magnetic field and neutron-ric...
We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to, or smaller than the pa...
Mechanism of delayed double ionization in a strong laser field
Centre de Physique Theoriqu Georgia Institute of Technology
2011/8/4
Abstract: When intense laser pulses release correlated electrons, the time delay between the ionizations may last more than one laser cycle. We show that this "Recollision-Excitation with Subsequent I...
