Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Harmonic analysis meets wave equation
谐波分析 符合 波动方程
2023/5/10
In this talk I plan to survey some progress on Hardy and BMO spaces, Riesz transforms, Bochner-Riesz means and spherical means by using the method of wave equation,and show interesting connections and...
Wave of the future:Terahertz chips a new way of seeing through matter
Wave of the future Terahertz chips seeing through matter
2017/3/13
Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, ha...
P-Wave Holographic Insulator/Superconductor Phase Transition
P-Wave Holographic Insulator/Superconductor Phase Transition
2010/12/24
Using a five dimensional AdS soliton in an Einstein-Yang-Mills theory with SU(2) gauge group we study p-wave holographic insulator/superconductor phase transition. To explore the phase structure of th...
Reply to Comment by Wolfgang Ketterle on "Electromagnetic Wave Dynamics in Matter-Wave Superradiant Scattering" (see arXiv:1010.3915)
Electromagnetic Wave Dynamics Matter-Wave Superradiant Scattering
2010/11/17
The comment by Wolfgang Ketterle [1] purports to present a viable model of superradiance in condensates.However, Ref. [1] is not able to explain the red/blue pump detuning asymmetry that was first obs...
Upper-hybrid wave driven Alfvenic turbulence in magnetized dusty plasmas
Upper-hybrid wave Alfvenic turbulence magnetized dusty plasmas
2010/11/12
The nonlinear dynamics of coupled electrostatic upper-hybrid (UH) and Alfven waves (AWs) is revisited in a magnetized electron-ion plasma with charged dust impurities. A pair of nonlinear equations [...
Recent ionospheric modification experiments with the 3.6 MW transmitter at the High Frequency Active Auroral Research Program (HAARP) facility in Alaska led to discovery of artificial ionization desc...
Engineering Biphoton Wave Packets with an Electromagnetically Induced Grating
Engineering Biphoton Wave Packets Electromagnetically Induced Grating
2010/11/5
We propose to shape biphoton wave packets with an electromagnetically induced grating in a four-level double-$\Lambda$ cold atomic system. We show that the induced hybrid grating plays an essential ro...
Interaction of the Electromagnetic S-Wave with the Thin Metal Film
Interaction the Electromagnetic S-Wave Thin Metal Film
2010/11/9
It is shown that for thin metal films, thickness of which does not exceed a thickness of a skin-layer, the problem allows analytical solution for any boundary conditions. The analysis of transmission...
Wave packet revivals in a graphene quantum dot in a perpendicular magnetic field
packet revivals graphene quantum dot perpendicular magnetic field
2010/10/27
We study the time-evolution of localized wavepackets in graphene quantum dots in a perpendicular magnetic field, focusing on the quasiclassical and revival periodicities, for different values of the m...
The scattering amplitude of ultracold atoms near the p-wave magnetic Feshbach Resonance
The scattering amplitude ultracold atoms p-wave magnetic Feshbach Resonance
2010/11/9
Most of the current theories on the p-wave superfluid in cold atomic gases are based on the effective-range theory for the two-body scattering, where the low energy p-wave scattering amplitude $f_1(k)...
Researchers in the US and Korea have discovered that igniting a carbon nanotube, coated in chemically flammable material, can trigger a high-speed wave to race along the tube at 10,000× the speed of t...
On wave turbulence in MHD
wave turbulence MHD
2009/11/12
We describe the fundamental differences between weak (wave) turbulence in incompressible and weakly compressible MHD at the level of three-wave interactions. The main difference is in the structure of...
