Stability of dark solitons in a bubble Bose-Einstein condensate
Raphael Wictky Sallatti, Lauro Tomio, Dmitry Pelinovsky +1
The stability of nonlinear waves on curved surfaces is a problem of widespread interest across physics. Here, we establish the stability criteria for dark solitons on a spherical B…

Distribution of eigenfrequencies for oscillations of the ground state in the Thomas--Fermi limit
P. G. Kevrekidis, D. E. Pelinovsky
In this work, we present a systematic derivation of the distribution of eigenfrequencies for oscillations of the ground state of a repulsive Bose-Einstein condensate in the semi-cl…
