Criticality and Spin Squeezing in the Rotational Dynamics of a BEC on a Ring Lattice
Michal Kolář, Tomáš Opatrný, Kunal K. Das
We examine the dynamics of circulating modes of a Bose-Einstein condensate confined in toroidal lattice. Nonlinearity due to interactions leads to criticality that separates oscill…
Matter, Energy, and Heat Transfer in a Classical Ballistic Atom Pump
Tommy A. Byrd, Kunal K. Das, Kevin A. Mitchell +2
A ballistic atom pump is a system containing two reservoirs of neutral atoms or molecules and a junction connecting them containing a localized time-varying potential. Atoms move t…
Mesoscopic Transport and Interferometry with Wavepackets of Ultracold atoms: Effects of Quantum Coherence and Interactions
Kunal K. Das
We propose a way to simulate mesoscopic transport processes with counter-propagating wavepackets of ultracold atoms in quasi one-dimensional (1D) waveguides, and show quantitative…
Ballistic atom pumps
Megan K. Ivory, Tommy A. Byrd, Andrew J. Pyle +4
We examine a classically-chaotic system consisting of two reservoirs of particles connected by a channel containing oscillating potential-energy barriers. We investigate whether su…
