Nonadiabatic Geometric Phase and Hannay Angle: A Squeezed State Approach
Jie Liu, Bambi Hu, Baowen Li
The geometric phases of the cyclic states of a generalized harmonic oscillator with nonadiabatic time-periodic parameters are discussed in the framework of squeezed state. A class…
On Schwarzschild Black Hole in Large N Matrix theory
Yi-hong Gao, Wei Zhang
D0-brane gas picture of Schwarzschild black hole (SBH) is considered in the large N regime of Matrix theory. An entropy formula, which reproduces the thermodynamics of SBH in the l…
Nonadiabatic geometric phase for the cyclic evolution of a time-dependent Hamiltonian system
Jie Liu, Bambi Hu, Baowen Li
The geometric phases of the cyclic states of a generalized harmonic oscillator with nonadiabatic time-periodic parameters are discussed in the framework of squeezed state. It is sh…
Asymptotic Dynamical Difference between the Nonlocal and Local Swift-Hohenberg Models
Guoguang Lin, Hongjun Gao, Jinqiao Duan +1
In this paper the difference in the asymptotic dynamics between the nonlocal and local two-dimensional Swift-Hohenberg models is investigated. It is shown that the bounds for the d…
Squeezed state dynamics of kicked quantum systems
Bambi Hu, Baowen Li, Jie Liu +1
We study kicked quantum systems by using the squeezed state approach. Taking the kicked quantum harmonic oscillator as an example, we demonstrate that chaos in an underlying classi…
Dynamic localization versus photon-assisted transport in semiconductor superlattices driven by dc-ac fields
W. -X. Yan, S. -Q. Bao, X. -G. Zhao
Via the numerical analysis on the intraband dynamics of optically excited semiconductor superlattices, we find that time-integrated squared THz emission signals can be used for pro…
