Solitons in tunnel-coupled repulsive and attractive condensates
Valery S. Shchesnovich, Solange B. Cavalcanti, Roberto A. Kraenkel
We study solitons in the condensate trapped in a double-well potential with far-separated wells, when the s-wave scattering length has different signs in the two parts of the conde…
Mixed-isotope Bose-Einstein condensates in Rubidium
Valery S. Shchesnovich, Anatoly M. Kamchatnov, Roberto A. Kraenkel
We consider the ground state properties of mixed Bose-Einstein condensates of 87Rb and 85Rb atoms in the isotropic pancake trap, for both signs of the interspecies scattering lengt…
General soliton matrices in the Riemann-Hilbert problem for integrable nonlinear equations
V. S. Shchesnovich, J. Yang
We derive the soliton matrices corresponding to an arbitrary number of higher-order normal zeros for the matrix Riemann-Hilbert problem of arbitrary matrix dimension, thus giving t…
Vortices in nonlocal Gross-Pitaevskii equation
Valery S Shchesnovich, Roberto A Kraenkel
We consider vortices in the nonlocal two-dimensional Gross-Pitaevskii equation with the interaction potential having the Lorentz-shaped dependence on the relative momentum. It is s…
