Dissipative solitons and vortices in polariton superfluids
Elena A. Ostrovskaya, Jasur Abdullaev, Anton S. Desyatnikov +2
We examine spatial localisation and dynamical stability of Bose-Einstein condensates of exciton-polaritons in microcavities under the condition of off-resonant spatially inhomogene…
Controlled transport of matter waves in two-dimensional optical lattices
Jasur Abdullaev, Dario Poletti, Elena A. Ostrovskaya +1
We propose a method for achieving dynamically controllable transport of highly mobile matter-wave solitons in a driven two-dimensional optical lattice. Our numerical analysis based…
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…
Dynamics of matter-wave solitons in a ratchet potential
Dario Poletti, Tristram J. Alexander, Elena A. Ostrovskaya +2
We study the dynamics of bright solitons formed in a Bose-Einstein condensate with attractive atomic interactions perturbed by a weak bichromatic optical lattice potential. The lat…
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…
Multi-component gap solitons in spinor Bose-Einstein condensates
Beata J. Dabrowska-Wuester, Elena A. Ostrovskaya, Tristram J. Alexander +1
We model the nonlinear behaviour of spin-1 Bose-Einstein condensates (BECs) with repulsive spin-independent interactions and either ferromagnetic or anti-ferromagnetic (polar) spin…
Quantum effects in the dynamical localization of Bose-Einstein condensates in optical lattices
Beata J. Dabrowska-Wuester, Sebastian Wuester, Ashton S. Bradley +2
We study quantum effects in the dynamics of a Bose-Einstein condensate loaded onto the edge of a Brillouin zone of a one-dimensional periodic potential created by an optical lattic…
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…
Interaction of matter-wave gap solitons in optical lattices
Beata J. Dabrowska, Elena A. Ostrovskaya, Yuri S. Kivshar
We study mobility and interaction of gap solitons in a Bose-Einstein condensate (BEC) confined by an optical lattice potential. Such localized wavepackets can exist only in the gap…
Dispersion control for matter waves and gap solitons in optical superlattices
Pearl J. Y. Louis, Elena A. Ostrovskaya, Yuri S. Kivshar
We present a numerical study of dispersion manipulation and formation of matter-wave gap solitons in a Bose-Einstein condensate trapped in an optical superlattice. We demonstrate a…
Matter-wave gap vortices in optical lattices
Elena A. Ostrovskaya, Yuri S. Kivshar
We predict the existence of spatially localized nontrivial topological states of the Bose-Einstein condensate with repulsive atomic interactions confined by an optical lattice. The…
