Evolution of localized pulses in the defocusing modified Korteweg-de Vries equation theory
L. F. Calazans de Brito, A. Gammal, A. M. Kamchatnov
In this work, we develop, in the Gurevich-Pitaevskii framework, an analytic theory for the evolution of localized pulses in the defocusing modified Korteweg-de Vries equation theor…

Dynamics of ring solitons in an expanding cloud of a Bose-Einstein condensate
A. M. Kamchatnov, B. I. Suleimanov, E. N. Tsoy
In this paper, we derive equations for the dynamics of ring dark solitons in an expanding cloud of a two-dimensional Bose-Einstein condensate. Assuming that the soliton's width is…
