Semiclassical Asymptotics for Weakly Nonlinear Bloch Waves
摘要:
We study the simultaneous semi-classical and adiabatic asymptotics for a class of (weakly) nonlinear Schrodinger equations with a fast periodic potential and a slowly varying confinement potential. A rigorous two-scale WKB-analysis, locally in time, is performed. The main nonlinear phenomenon is a modi. cation of the Berry phase.
