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…

Rogue waves of Ultra-High Peak Amplitude: A Mechanism for Reaching up to Thousand Times the Background Level
Wen-Rong Sun, Lei Liu, P. G. Kevrekidis
We unveil a mechanism enabling a fundamental rogue wave, expressed by a rational function of fourth degree, to reach a peak amplitude as high as a thousand times the background lev…
