Controlling the transverse instability of dark solitons and nucleation of vortices by a potential barrier

Manjun Ma, R. Carretero-Gonzalez, P. G. Kevrekidis +2

We study possibilities to suppress the transverse modulational instability (MI) of dark-soliton stripes in two-dimensional (2D) Bose-Einstein condensates (BECs) and self-defocusing…
