Berry's Phase Induced Bose-Einstein condensation into a Vortex State
M. Olshanii, M. Naraschewski
The existence of a geometric phase in magnetic traps can be used to Bose condense a magnetically trapped atomic gas into a vortex state. We propose an experimental setup where a ma…
de-Broglie Wave-Front Engineering
M. Olshanii, N. Dekker, C. Herzog +1
We propose a simple method for the deterministic generation of an arbitrary continuous quantum state of the center-of-mass of an atom. The method's spatial resolution gradually inc…
Finite-Temperature Collective Excitation of a Bose-Einstein Condensate
Maxim Olshanii
We derive a simple formula for the finite-temperature shifts of the collective excitations of a Bose-Einstein condensate. To test the validity of our treatment we apply it to expla…
Atomic Scattering in Presence of an External Confinement and a Gas of Impenetrable Bosons
Maxim Olshanii
We calculate, within the pseudopotential approximation, a one-dimensional scattering amplitude and effective one-dimensional interaction potential for atoms confined transversally…
