Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Microphysical and non-thermal processes in the circumgalactic medium: turbulence, magnetic fields and cosmic rays
银河系 周介质 微物理 非热过程 湍流 磁场 宇宙射线
2023/4/18
Multiphase gas structure is ubiquitous in our universe. Recent observations suggest that large quantities of cool (10^4 K) gas are detected in the circumgalactic medium (CGM) of galaxy halos, which ex...
Peristaltic flow of a Newtonian fluid through a porous medium in a vertical tube under the effect of a magnetic field
Heat Transfer Magnetic Field Newtonian Fluid Porous Medium Reynolds Number
2015/7/21
In this paper, we studied the effects of heat transfer and magnetic field with peristaltic flow of a viscous incompressible Newtonian fluid through a porous medium in a vertical tube under the assumpt...
Polariton waves in nonlinear dielectric medium
dielectric medium phonon-polariton spectrum soliton cnoidal wave all-optical logic gates
2012/5/29
The phonon-polariton spectrum in dielectric medium with the third order nonlinearity was theoretically obtained. Dependence of number of polariton spectrum branches on intensity of electromagnetic fie...

Evidence Shape Co-existence medium spin 76Rb
2011/7/21
Four previously known rotational bands in 76Rb have been extended to moderate spins using the Gammasphere and Microball gamma ray and charged particle detector arrays and the 40Ca(40Ca,3pn) reaction a...
Femtosecond pulses in a dense two-level medium: Spectral transformations, transient processes, and collisional dynamics
Femtosecond pulses dense two-level medium Spectral transformations transient processes collisional dynamics
2011/8/5
Abstract: Propagation of ultrashort optical pulses in a dense resonant medium is considered in the semiclassical limit. In our analysis, we place emphasis on several main points. First, we study trans...
Ultrathin optical switch based on a liquid crystal/silver nanoparticles mixture as a tunable indefinite medium
Ultrathin optical switch liquid crystal silver nanoparticles tunable indefinite medium
2011/8/2
Abstract: We predict that a liquid crystal/silver nanoparticles mixture can be designed so that, in a frequency range, its effective ordinary and extraordinary permittivities have real parts of differ...

Particle acceleration stimulated emission of radiation
2011/8/31
In a recent Letter,V. Berezovsky, H. Alam, and L. Sch鋍hter have reported 揳cceleration of electrons moving in free space near an active Nd:YAG slab? The reported mechanism is particle acceleration by s...
Plane waves in a moving medium and the Lorentz covariance of Minkowski's photon and electromagnetic momentum-energy four-vectors
invariance of phase, wave four-vector, moving dielectric medium, light momentum in medium
2011/8/30
In this paper, invariant forms of refractive index, phase velocity, and group velocity are defined for plane waves in a moving medium. From the covariant wave four-vector combined with Einstein’s ligh...
