Stroboscopic aliasing in long-range interacting quantum systems
Shane P. Kelly, Eddy Timmermans, Jamir Marino +1
We unveil a mechanism for generating oscillations with arbitrary multiplets of the period of a given external drive, in long-range interacting quantum many-particle spin systems. T…
BEC "level" for measuring small forces
S. G. Bhongale, Eddy Timmermans
We propose a device that consists of a trapped two-component phase- separated Bose-Einstein condensate to measure small forces and map weak potential energy landscapes. The resolut…
Acoustic attenuation rate in the Fermi-Bose model with a finite-range fermion-fermion interaction
Bogdan Mihaila, Sergio Gaudio, Kevin S. Bedell +2
We study the acoustic attenuation rate in the Fermi-Bose model describing a mixtures of bosonic and fermionic atom gases. We demonstrate the dramatic change of the acoustic attenua…
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,…
Acoustic attenuation probe for fermion superfluidity in ultracold atom gases
Sergio Gaudio, B. Mihaila, K. B. Blagoev +2
Dilute gas Bose-Einstein condensates (BEC's), currently used to cool fermionic atoms in atom traps, can also probe the superfluidity of these fermions. The damping rate of BEC-acou…
