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…
Ground state wavefunction of the quantum Frenkel-Kontorova model
Bambi Hu, Baowen Li
The wavefunction of an incommensurate ground state for a one-dimensional discrete sine-Gordon model -- the Frenkel-Kontorova (FK) model -- at zero temperature is calculated by the…
Parallel updating cellular automaton models of driven diffusive Frenkel-Kontorova-type systems
Bing-Hong Wang, Y. R. Kwong, P. M. Hui +1
Three cellular automaton (CA) models of increasing complexity are introduced to model driven diffusive systems related to the generalized Frenkel-Kontorova (FK) models recently pro…
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…
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…
Cantori and dynamical localization in the Bunimovich Stadium
Fausto Borgonovi, Paolo Conti, Daniela Rebuzzi +2
Classical and quantum properties of the Bunimovich stadium in the diffusive regime are reviewed. In particular, the quantum properties are directly investigated using an approximat…
Analytical Results For The Steady State Of Traffic Flow Models With Stochastic Delay
Bing-Hong Wang, Lei Wang, P. M. Hui +1
Exact mean field equations are derived analytically to give the fundamental diagrams, i.e., the average speed - car density relations, for the Fukui-Ishibashi one-dimensional traff…
Effects of a Magnetic Field on a Modulated Phase
Bambi Hu, Jian Zhou
The effects of a magnetic field on a modulated phase is studied. A modulated phase is found to have two critical fields and . For a large enough magnetic field. $H_1…
A Frenkel-Kontorova Model with Two Spring Constants: New Phases and Phase Transitions
Bambi Hu, Jian Zhou
A discrete Frenkel-Kontorova model with two alternate spring constants and is studied. It is found that this model has many surprising behaviours. The continuum ver…
