Trapped Two-Dimensional Fermi Gases with Population Imbalance
Bert Van Schaeybroeck, Achilleas Lazarides, Serghei Klimin +1
We study population imbalanced Fermi mixtures under quasi-two-dimensional confinement at zero temperature. Using mean-field theory and the local-density approximation, we study the…
Novel Methods to Create Multielectron Bubbles in Superfluid Helium
J. Fang, Anatoly. E. Dementyev, J. Tempere +1
An equilibrium multielectron bubble in liquid helium is a fascinating object with a spherical two-dimensional electron gas on its surface. We describe two ways of creating them. ME…
Path integral approach to Asian options in the Black-Scholes model
Jeroen P. A. Devreese, Damiaan Lemmens, Jacques Tempere
We derive a closed-form solution for the price of an average price as well as an average strike geometric Asian option, by making use of the path integral formulation. Our results…
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…
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…
