Manipulating the Mott lobes: optical lattice bosons coupled to an array of atomic quantum dots
Damian Wozniak, Florian Magnus Dobler, Anna Posazhennikova
We analyze quantum phase transitions in a system of optical lattice bosons coupled to an array of atomic quantum dots, or pseudospins-1/2. The system parallels the Bose-Hubbard mod…
Fluctuation-damping of isolated, oscillating Bose-Einstein condensates
Tim Lappe, Anna Posazhennikova, Johann Kroha
Experiments on the nonequilibrium dynamics of an isolated Bose-Einstein condensate (BEC) in a magnetic double-well trap exhibit a puzzling divergence: While some show dissipation-f…
The interplay of phonon and exciton-mediated superconductivity in hybrid semiconductor-superconductor structures
Petros Skopelitis, Evgenia D. Cherotchenko, Alexey V. Kavokin +1
We predict a strong enhancement of the critical temperature in a conventional Bardeen-Cooper-Schrieffer (BCS) superconductor in the presence of a bosonic condensate of exciton-pola…
