Solution of the Riemann problem for polarization waves in a two-component Bose-Einstein condensate
S. K. Ivanov, A. M. Kamchatnov, T. Congy +1
We provide a classification of the possible flow of two-component Bose-Einstein condensates evolving from initially discontinuous profiles. We consider the situation where the dyna…
Riemann problem for the photon fluid: self-steepening effects
S. K. Ivanov, A. M. Kamchatnov
We consider the Riemann problem of evolution of initial discontinuities for the photon fluid propagating in a normal dispersion fiber with account of self-steepening effects. The d…
Evolution of initial discontinuities in the Riemann problem for the Kaup-Boussinesq equation with positive dispersion
T. Congy, S. K. Ivanov, A. M. Kamchatnov +1
We consider the space-time evolution of initial discontinuities of depth and flow velocity for an integrable version of the shallow water Boussinesq system introduced by Kaup. We f…
Expansion Dynamics of a Two-Component Quasi-One-Dimensional Bose-Einstein Condensate: Phase Diagram, Self-Similar Solutions, and Dispersive Shock Waves
S. K. Ivanov, A. M. Kamchatnov
We investigate the expansion dynamics of a Bose-Einstein condensate that consists of two components and is initially confined in a quasi-one-dimensional trap. We classify the possi…
