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...
Anisotropic spin diffusion in trapped Boltzmann gases
Trapped bose gas mixture dynamics grain boltzmann constant
2014/12/20
Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type effects...
A geometric derivation of the linear Boltzmann equation for a particle interacting with a Gaussian random field
Processes in random environments Quantum field theory Coherent states Kinetic theory of gases

Abstract: The linear Boltzmann equation is derived from a microscopic quantum model of a particle interacting, in the weak coupling limit, with a translation invariant and centered Gaussian random fie...
Abstract: Difference Boltzmann Equation is derived in a plane wavelets representation with account of two-particle correlations. It is shown that the set of plane wavelet orthonormal functions is comp...

自然界和工程领域中的许多物理现象的发生通常涵盖几个数量级的几何空间及时间范围, 我们将其统称为多尺度物理现象. 在模拟多尺度问题时, 如果仅采用宏观方法, 则会存在一些不足, 如无法预知微小部分的细节以及引入复杂的经验关联式; 如果仅采用介观/微观方法, 则需要消耗大量的计算资源. 构造宏观-介观、宏观-微观、宏观-介观-微观等多种层次上方法的耦合体系, 可以在很大程度上克服这些不足. 构造了宏观...
