Quantum dissipative dynamics of driven Duffing oscillator near attractors
Wei Feng, Lingzhen Guo
We investigate the quantum dissipative dynamics near the stable states (attractors) of a driven Duffing oscillator. A refined perturbation theory that can treat two perturbative pa…

Discrete nonlinear Schrödinger type equations: Solutions and continuum limits
Song-lin Zhao, Xiao-hui Feng, Wei Feng
As local and nonlocal reductions of a discrete second-order Ablowitz-Kaup-Newell-Segur equation, two discrete nonlinear Schrödinger type equations are considered. Through the bilin…

Local and nonlocal complex discrete and semi-discrete sine-Gordon equations and solutions
Xiao-bo Xiang, Wei Feng, Song-lin Zhao
In this paper, local and nonlocal complex reduction of a discrete and a semi-discrete negative order Ablowitz-Kaup-Newell- Segur equations is studied. Cauchy matrix type solutions,…
