Kicked-rotor quantum resonances in position space: Application to systems of experimental interest
quantum resonances position space experimental interest
<
2010/10/21
In a previous article [1], we have presented an original approach of the quantum resonances of the kicked rotor. We have described the quantum resonances in position space, for strongly localized wave...

We discuss spectral and resonance properties of a Hamiltonian describing motion of an electron moving on a \hybrid surface" consisting on a hal ine attached by its endpoints to a plane under in uence ...
We propose a mechanism to rectify charge transport in the semiclassical Holstein model. It is
shown that localised initial conditions, associated with a polaron solution, in conjunction with a nonrev...

2014/3/3
通过数值模拟的方法对磁场作用下的双扩散液层热毛细对流进行了研究, 模型中同时考虑了热毛细效应和溶质毛细效应的存在. 研究结果显示, 外部磁场能够有效削弱液层内热毛细对流的强度, 改变热毛细对流的对流结构; 随着磁场强度的增大, 液层内热毛细对流的对流强度逐渐减小, 热质传递过程中扩散效应逐渐得到增强; 最终, 溶质浓度沿水平方向呈梯度分布. 因此, 当磁场强度足够大时能够实现晶体生长中所需的纯扩散...
