A numerical and symbolical approximation of the Nonlinear Anderson Model
Yevgeny Krivolapov, Shmuel Fishman, Avy Soffer
A modified perturbation theory in the strength of the nonlinear term is used to solve the Nonlinear Schroedinger Equation with a random potential. It is demonstrated that in some c…
Double humped states in the nonlinear Schroedinger equation with a random potential
Hagar Veksler, Yevgeny Krivolapov, Shmuel Fishman
The role of double humped states in spreading of wave packets for the nonlinear Schroedinger equation (NLSE) with a random potential is explored and the spreading mechanism is unra…
Spreading for the generalized nonlinear Schroedinger equation with disorder
Hagar Veksler, Yevgeny Krivolapov, Shmuel Fishman
The dynamics of an initially localized wavepacket is studied for the generalized nonlinear Schroedinger Equation with a random potential, where the nonlinearity term is |ψ|^p*ψand…
Perturbation theory for the Nonlinear Schroedinger Equation with a random potential
Shmuel Fishman, Yevgeny Krivolapov, Avy Soffer
A perturbation theory for the Nonlinear Schroedinger Equation (NLSE) in 1D on a lattice was developed. The small parameter is the strength of the nonlinearity. For this purpose sec…
