Collisional cooling of ultra-cold atom ensembles using Feshbach resonances
L. Mathey, Eite Tiesinga, Paul S. Julienne +1
We propose a new type of cooling mechanism for ultra-cold fermionic atom ensembles, which capitalizes on the energy dependence of inelastic collisions in the presence of a Feshbach…
Heavily Damped Motion of One-Dimensional Bose Gases in an Optical Lattice
Ippei Danshita, Charles W. Clark
We study the dynamics of strongly correlated one-dimensional Bose gases in a combined harmonic and optical lattice potential subjected to sudden displacement of the confining poten…
Creating a supersolid in one-dimensional Bose mixtures
L. Mathey, Ippei Danshita, Charles W. Clark
We identify a one-dimensional supersolid phase in a binary mixture of near-hardcore bosons with weak, local inter-species repulsion. We find realistic conditions under which such a…
Experimentally accessible reentrant phase transitions in double-well optical lattices
Ippei Danshita, Carlos A. R. Sa de Melo, Charles W. Clark
We study the quantum phases of bosons confined in a combined potential of a one-dimensional double-well optical lattice and a parabolic trap. We apply the time-evolving block decim…
Quantum phases of bosons in double-well optical lattices
Ippei Danshita, James E. Williams, Carlos A. R. Sa de Melo +1
We study the superfluid to Mott insulator transition of bosons in a two-legged ladder optical lattice, of a type accessible in current experiments on double-well optical lattices.…
Lifshitz-like transition and enhancement of correlations in a rotating bosonic ring lattice
Ana Maria Rey, Keith Burnett, Indubala I. Satija +1
We study the effects of rotation on one-dimensional ultra-cold bosons confined to a ring lattice. For commensurate systems, at a critical value of the rotation frequency, an infini…
