Nonlinear delocalization on disordered Stark ladder
arXiv:0903.2103 · doi:10.1140/epjb/e2009-00265-5
Abstract
We study effects of weak nonlineary on localization of waves in disordered Stark ladder corresponding to propagation in presence of disorder and a static field. Our numerical results show that nonlinearity leads to delocalization with subdiffusive spreading along the ladder. The exponent of spreading remains close to its value in absence of the static field.
