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…

Supersonic Flow Past an Obstacle in a Quasi-Two-Dimensional Lee-Huang-Yang Quantum Fluid
G. H. dos Santos, L. F. Calazans de Brito, A. Gammal +1
A supersonic flow past an obstacle can generate a rich variety of wave excitations. This paper investigates, both analytically and numerically, two types of excitations generated b…
