Angular EPR paradox
Joerg B Goette, Sonja Franke-Arnold, Stephen M. Barnett
The violation of local uncertainty relations is a valuable tool for detecting entanglement, especially in multi-dimensional systems. The orbital angular momentum of light provides…
A large magnetic storage ring for Bose-Einstein condensates
A. S. Arnold, C. S. Garvie, E. Riis
Cold atomic clouds and Bose-Einstein condensates have been stored in a 10cm diameter vertically-oriented magnetic ring. An azimuthal magnetic field enables low-loss propagation of…
Non-Abelian gauge potentials for ultra-cold atoms with degenerate dark states
J. Ruseckas, G. Juzeliunas, P. Oehberg +1
We show that the adiabatic motion of ultra-cold, multi-level atoms in spatially varying laser fields can give rise to effective non-Abelian gauge fields if degenerate adiabatic eig…
Effective magnetic fields in degenerate atomic gases induced by light beams with orbital angular momenta
G. Juzeliunas, P. Ohberg, J. Ruseckas +1
We investigate the influence of two resonant laser beams on the mechanical properties of degenerate atomic gases. The control and probe beams of light are considered to have Orbita…
