The stochastic discrete nonlinear Schrödinger equation: microscopic derivation and finite-temperature phase transition
Mahdieh Ebrahimi, Barbara Drossel, Wolfram Just
We study a stochastic version of the one-dimensional discrete nonlinear Schr{ö}dinger equation (DNSE), which is derived from first principles, and thus possesses all the properties…

Dynamics of localized states in the stochastic discrete nonlinear Schrödinger equation
Mahdieh Ebrahimi, Barbara Drossel, Wolfram Just
We revisit aspects of dynamics and stability of localized states in the deterministic and stochastic discrete nonlinear Schrödinger equation. By a combination of analytic and numer…
