Inter-Condensate Tunneling in Bose-Einstein Condensates with Feshbach Resonances
Eddy Timmermans, Paolo Tommasini, Robin Cote +2
Recently, effects of Feshbach resonances in atom-atom interactions were observed by varying the external magnetic field of an atomic Bose-Einstein condensate (BEC). We point out th…
Feshbach Resonance and Hybrid Atomic/Molecular BEC-Systems
Paolo Tommasini, Eddy Timmermans, Mahir Hussein +1
The interactions responsible for Feshbach resonances in binary atom collisions produce a condensate of molecules in the atomic BEC-system. We discuss the `ground state' of the cond…
Phase separation of Bose-Einstein condensates
Eddy Timmermans
The zero-temperature system of two dilute overlapping Bose-Einstein condensates is unstable against long wavelength excitations if the interaction strength between the distinguisha…
Thomas-Fermi Description of Incoherent Light Scattering from an Atomic-Trap BEC
Eddy Timmermans, Paolo Tommasini
We present a Thomas-Fermi treatment of resonant incoherent scattering of low-intensity light by a dilute spatially confined Bose-Einstein condensate. The description gives simple a…
Superfluidity in sympathetic cooling with atomic Bose condensates
E. Timmermans, R. Cote
The dynamical structure of an atomic Bose-Einstein condensate limits the efficiency of the condensate in cooling slow impurity atoms. To illustrate the point, we show that an impur…
Quasi-Homogeneous Dynamical Structure Factor for Atomic-Trap Bose Condensates
Eddy Timmermans, Paolo Tommasini
The essence of the Thomas-Fermi model is the assumption that the local behavior of a many-body system can be approximated by that of a homogeneous system. In this paper, we present…
