The instabilities beyond modulational type in a repulsive Bose-Einstein condensate with a periodic potential
Wen-Rong Sun, Jin-Hua Li, Lei Liu +1
The instabilities of the nontrivial phase elliptic solutions in a repulsive Bose-Einstein condensate (BEC) with a periodic potential are investigated. Based on the defocusing nonli…

Time-localized dark modes generated by zero-wavenumber-gain modulational instability
Lei Liu, Wen-Rong Sun, Boris A. Malomed +1
In this work we report on the emergence of a novel type of solitary waves, viz., time-localized solitons in integrable and non-integrable variants of the massive Thirring models an…
