Heat conduction in one-dimensional Yukawa chains
Bambi Hu, Haibin Li, Bai-Song Xie
Heat conduction in one-dimensional Yukawa chains is investigated. It is shown numerically that it has the abnormal heat conduction which is proportional to the system size. Effects…
Fejer average and the short term behaviors of a wave packet in infinite square well
Quan-Hui Liu, Wei-Hong Qi, Li-Ping Fu +1
The first two period behaviors of a quantum wave packet in an infinite square well potential is studied. First, the short term behavior of expectation value of a quantity on an equ…
Parametric Simultons in Nonlinear Lattices
Bambi Hu, Guoxiang Huang
Parametric simultaneous solitary wave (simulton) excitations are shown possible in nonlinear lattices. Taking a one-dimensional diatomic lattice with a cubic potential as an exampl…
Coherence resonance near blowout bifurcation in nonlinear dynamical systems
Bambi Hu, Changsong Zhou
Previous studies have shown that noise can induce coherence resonance in some nonlinear dynamical systems close to a bifurcation of a periodic motion, such as in excitable systems.…
Non-Monotone Characteristic of Spectral Statistics in the Transition between Poisson and Gauss
Hiroshi Hasegawa, Baowen Li, Jian-Zhong Ma +1
We have computed the spectral number variances of an extended random matrix ensemble predicted by Guhr's supersymmetry formula, showing a non-monotone increase of the curves that a…
Universal statistics of wave functions in chaotic and disordered systems
Bambi Hu, Baowen Li, Weng-ge Wang
We study a new statistics of wave functions in several chaotic and disordered systems: the random matrix model, band random matrix model, the Lipkin model, chaotic quantum billiard…
