Fermion-mediated interactions in a dilute Bose-Einstein condensate
D. H. Santamore, Eddy Timmermans
We develop a diagrammatic perturbation treatment to calculate the zero-temperature equation of state of the dilute gas mixture of a single spin component Bose-Einstein condensate (…
Coherent macroscopic quantum tunneling in boson-fermion mixtures
D. Mozyrsky, I. Martin, E. Timmermans
We show that the cold atom systems of simultaneously trapped Bose-Einstein condensates (BEC's) and quantum degenerate fermionic atoms provide promising laboratories for the study o…
Self-localized impurities embedded in a one dimensional Bose-Einstein condensate and their quantum fluctuations
Krzysztof Sacha, Eddy Timmermans
We consider the self-localization of neutral impurity atoms in a Bose-Einstein condensate in a 1D model. Within the strong coupling approach, we show that the self-localized state…
Small polarons in dilute gas Bose-Einstein condensates
Fernando M. Cucchietti, Eddy Timmermans
A neutral impurity atom immersed in a dilute Bose-Einstein condensate (BEC) can have a bound ground state in which the impurity is self-localized. In this small polaron-like state,…
Sympathetic cooling route to Bose-Einstein condensate and Fermi-liquid mixtures
Robin Cote`, Roberto Onofrio, Eddy Timmermans
We discuss a sympathetic cooling strategy that can successfully mitigate fermion-hole heating in a dilute atomic Fermi-Bose mixture and access the temperature regime in which the f…
Collective excitations of low density fermion-boson quantum-liquid mixtures
D. H. Santamore, Eddy Timmermans
We investigate the collective excitations of a low temperature dilute gas mixture that consists of a Bose-Einstein condensate and a Fermi-gas that is a normal (i.e. non-superfluid)…
