Nonlinearity-induced localization in a periodically driven semidiscrete system
Nonlinearity-induced localization in a periodically driven semidiscrete system
We demonstrate that nonlinearity plays a constructive role in supporting the robustness of dynamical localization in a system which is discrete in one dimension and continuous in the orthogonal one. In the linear regime, time-periodic modulation of the gradient strength along the discrete axis leads to the usual rapid spread …
