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.…
Tunneling Dynamics of Bose-Einstein Condensates with Feshbach Resonances
Bambi Hu, Le-Man Kuang
We study tunneling dynamics of atomic pairs in Bose-Einstein condensates with Feshbach resonances. It is shown that the tunneling of the atomic pairs depends on not only the tunnel…
Quantum Tunneling and Quantum-Classical Transitions in Large Spin Systems
Bambi Hu, De-gang Zhang, Bo-zang Li
We have studied quantum tunneling of large spins in a biaxial spin system and in a single-axial spin system with a transverse magnetic field. The asymptotically exact eigenvalues a…
Disturbance spreading in incommensurate and quasiperiodic systems
Bambi Hu, Baowen Li, Peiqing Tong
The propagation of an initially localized excitation in one dimensional incommensurate, quasiperiodic and random systems is investigated numerically. It is discovered that the time…
