Symmetry breaking and singularity structure in Bose-Einstein condensates

K. A. Commeford, M. A. Garcia-March, A. Ferrando +1

We determine the trajectories of vortex singularities that arise after a single vortex is broken by a discretely symmetric impulse in the context of Bose-Einstein condensates in a…

Macroscopic superposition states of ultracold bosons in a double-well potential

M. A. Garcia-March, D. R. Dounas-Frazer, Lincoln D. Carr

We present a thorough description of the physical regimes for ultracold bosons in double wells, with special attention paid to macroscopic superpositions (MSs). We use a generaliza…

Angular Pseudomomentum Theory for the Generalized Nonlinear Schrödinger Equation in Discrete Rotational Symmetry Media

M. -Á. García-March, A. Ferrando, M. Zacarés +2

We develop a complete mathematical theory for the symmetrical solutions of the generalized nonlinear Schrödinger equation based on the new concept of angular pseudomomentum. We con…

Dynamical Realization of Macroscopic Superposition States of Cold Bosons in a Tilted Double Well

Lincoln D. Carr, D. R. Dounas-Frazer, Miguel-Ángel García-March

We present exact expressions for the quantum sloshing of Bose-Einstein condensates in a tilted two-well potential. Tunneling is suppressed by a small potential difference between w…

Ultracold Bosons in a Tilted Multi-level Double-Well Potential

D. R. Dounas-Frazer, A. M. Hermundstad, L. D. Carr

The N -body problem in a double well requires new features for quantum information processing, macroscopic quantum superposition, and other fundamental studies of quantum many body…
