Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On nonlinear Schrodinger-type equations with nonlinear damping
非线性阻尼 非线性 薛定谔型方程
2023/4/25
In this talk，I will introduce equations of nonlinear Schrodinger-type augmented by nonlinear damping terms. The nonlinear damping can prevent finite time blow-up in several situations. The solution of...
Landau damping of spin waves in trapped Boltzmann gases
Ultracold gas boltzmann spatial dependence
2014/12/20
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time evolutio...

2012/2/28
A theoretical investigation of photoabsorption and photoionization of Fe^{14+} extending beyond an earlier frame transformation R-matrix implementation is performed using a fully-correlated, Breit-Pau...
Plasma damping effects on the radiative energy loss of relativistic particles
Landau-Pomeranchuk-Migdal effect Ter-Mikaelian effect radiative energy loss
2011/7/21
The energy loss of a relativistic charge undergoing multiple scatterings while traversing an infinite, polarizable and absorptive plasma is investigated.
Oscillations of hot, young neutron stars: Gravitational wave frequencies and damping times
Oscillations of hot young neutron stars
2011/7/21
We study how the frequencies and damping times of oscillations of a newly born, hot proto-neutron star depend on the physical quantities which characterize the star quasi-stationary evolution which fo...

Samll BGK waves nonlinear Landau damping
2011/9/15
Consider Vlasov-Poisson system with a fixed ion background and periodic condition on the space variables, in any dimension d 2. First, we show that for general homogeneous equilibrium and any period...
Frictional damping in radiative electrodynamics and its scaling to macroscopic systems
Abraham-Lorentz-Dirac equation, radiation force, Unruh radiation,frictional dissipation
2011/8/30
Radiation force in Abraham-Lorentz-Dirac equation is revisited for possible signature of irreversible action in the dynamics. The analysis shows that the classical electron can ‘dissipate’ out a certa...
Measurement of damping and temperature: Precision bounds in Gaussian dissipative channels
Measurement damping temperature Precision bounds Gaussian dissipative channels
2010/10/29
We present a comprehensive analysis of the performance of different classes of Gaussian states in the estimation of Gaussian phase-insensitive dissipative channels. In particular, we investigate the ...
