Distributed vorticity model for vortex molecule dynamics
Sarthak Choudhury, Joachim Brand
We analyze the effect of a hard wall trapping potential on the dynamics of a vortex molecule in a two-component Bose-Einstein condensate with linear coherent coupling. A vortex mol…

Rotational pendulum dynamics of a vortex molecule in a channel geometry
Sarthak Choudhury, Joachim Brand
A vortex molecule is a topological excitation in two coherently coupled superfluids consisting of a vortex in each superfluid connected by a domain wall of the relative phase, also…

Collisions of solitary waves in condensates beyond mean-field theory
Aparna Sreedharan, Sarthak Choudhury, Rick Mukherjee +2
Bright solitary waves in a Bose-Einstein condensate contain thousands of identical atoms held together despite their only weakly attractive contact interactions. They nonetheless b…
