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,…
BCS-BEC crossover with a finite-range interaction
Meera M. Parish, Bogdan Mihaila, Eddy M. Timmermans +2
We study the crossover from BEC to BCS pairing for dilute systems but with a realistic finite-range interaction. We exhibit the changes in the excitation spectrum that provide a cl…
