Spinor Bose-Einstein condensate flow past an obstacle
A. S. Rodrigues, P. G. Kevrekidis, R. Carretero-González +4
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions and find t…
Matter-wave solitons with a periodic, piecewise-constant nonlinearity
A. S. Rodrigues, P. G. Kevrekidis, Mason A. Porter +3
Motivated by recent proposals of ``collisionally inhomogeneous'' Bose-Einstein condensates (BECs), which have a spatially modulated scattering length, we study the existence and st…
Symmetry Breaking in Symmetric and Asymmetric Double-Well Potentials
G. Theocharis, P. G. Kevrekidis, D. J. Frantzeskakis +1
Motivated by recent experimental studies of matter-waves and optical beams in double well potentials, we study the solutions of the nonlinear Schrödinger equation in such a context…
