Feynman path-integral treatment of the BEC-impurity polaron
J. Tempere, W. Casteels, M. K. Oberthaler +2
The description of an impurity atom in a Bose-Einstein condensate can be cast in the form of Frohlich's polaron Hamiltonian, where the Bogoliubov excitations play the role of the p…
Froehlich Polaron and Bipolaron: Recent Developments
Jozef Devreese, Sasha Alexandrov
It is remarkable how the Froehlich polaron, one of the simplest examples of a Quantum Field Theoretical problem, as it basically consists of a single fermion interacting with a sca…
Co-existence of the Meissner and vortex-state on a superconducting spherical shell
J. Tempere, V. N. Gladilin, I. F. Silvera +2
We show that on superconducting spherical nanoshells, the co-existence of the Meissner state with a variety of vortex patterns drives the phase transition to higher magnetic fields…
The effect of population imbalance on the Berezinskii-Kosterlitz-Thouless phase transition in a superfluid Fermi gas
J. Tempere, S. N. Klimin, J. T. Devreese
The Berezinskii-Kosterlitz-Thouless (BKT) mechanism describes the breakdown of superfluidity in a two-dimensional Bose gas or a two-dimensional gas of paired fermions. In the latte…
