Macroscopic quantum self-trapping in a Bose-Josephson junction with fermions
S. F. Caballero Benitez, E. A. Ostrovskaya, M. Gulacsi +1
We study the macroscopic quantum self-trapping effect in a mixture of Bose-Einstein condensate and a large number of quantum degenerate fermions, trapped in a double-well potential…
Nonlinearity-assisted quantum tunneling in a matter-wave interferometer
Chaohong Lee, Elena A. Ostrovskaya, Yuri S. Kivshar
We investigate the {\em nonlinearity-assisted quantum tunneling} and formation of nonlinear collective excitations in a matter-wave interferometer, which is realised by the adiabat…
Three-dimensional matter-wave vortices in optical lattices
Tristram J. Alexander, Elena A. Ostrovskaya, Andrey A. Sukhorukov +1
We predict the existence of spatially localized nontrivial vortex states of a Bose-Einstein condensate with repulsive atomic interaction confined by a three-dimensional optical lat…
