Towards the complete description of stationary states of a Bose-Einstein condensate in a one-dimensional quasiperiodic lattice: A coding approach
G. L. Alfimov, A. P. Fedotov, Ya. A. Murenkov +1
We consider stationary states of an effectively one-dimensional Bose-Einstein condensate in a quasiperiodic lattice. We formulate sufficient conditions for a one-to-one corresponde…

On non-existence of continuous families of stationary nonlinear modes for a class of complex potentials
Dmitry A. Zezyulin, Alexander O. Slobodyanyuk, Georgy L. Alfimov
There are two cases when the nonlinear Schrödinger equation (NLSE) with an external complex potential is well-known to support continuous families of localized stationary modes: th…
