Symmetry-Breaking and Symmetry-Restoring Dynamics of a Mixture of Bose-Einstein Condensates in a Double Well
Indubala I Satija, Philip Naudus, Radha Balakrishnan +3
We study the coherent nonlinear tunneling dynamics of a binary mixture of Bose-Einstein condensates in a double-well potential. We demonstrate the existence of a new type of mode a…
Phase transitions, entanglement and quantum noise interferometry in cold atoms
Florian Mintert, Ana Maria Rey, Indubala I. Satija +1
We show that entanglement monotones can characterize the pronounced enhancement of entanglement at a quantum phase transition if they are sensitive to long-range high order correla…
Vortices and Ring Solitons in Bose-Einstein Condensates
L. D. Carr, Charles W. Clark
The form and stability properties of axisymmetric and spherically symmetric stationary states in two and three dimensions, respectively, are elucidated for Bose-Einstein condensate…
Linear spin waves in a trapped Bose gas
T. Nikuni, J. E. Williams, C. W. Clark
An ultra-cold Bose gas of two-level atoms can be thought of as a spin-1/2 Bose gas. It supports spin-wave collective modes due to the exchange mean field. Such collective spin osci…
Anomalous modes drive vortex dynamics in confined Bose-Einstein condensates
David L. Feder, Anatoly A. Svidzinsky, Alexander L. Fetter +1
The dynamics of vortices in trapped Bose-Einstein condensates are investigated both analytically and numerically. In axially symmetric traps, the critical rotation frequency for th…
Imaging the phase of an evolving Bose-Einstein condensate wavefunction
J. E. Simsarian, J. Denschlag, Mark Edwards +6
We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical pha…
