Vortex solitons in dipolar Bose-Einstein Condensates
I. Tikhonenkov, B. A. Malomed, A. Vardi
We predict solitary vortices in quasi-planar condensates of dipolar atoms, polarized parallel to the confinement direction, with the effective sign of the dipole-dipole interaction…
Confinement controlled dissociation of a molecular Bose-Einstein condensate
I. Tikhonenkov, A. Vardi
We study the collective two-channel dissociation dynamics of a molecular Bose-Einstein condensate into bosonic fragments under tight harmonic confinement. Bose-stimulated dissociat…
Matter-wave squeezing and the generation of SU(1,1) and SU(2) coherent-states via Feshbach resonances
I. Tikhonenkov, E. Pazy, Y. B. Band +1
Pair operators for boson and fermion atoms generate SU(1,1) and SU(2) Lie algebras, respectively. Consequently, the pairing of boson and fermion atoms into diatomic molecules via F…
Anisotropic solitons in dipolar Bose-Einstein Condensates
I. Tikhonenkov, B. A. Malomed, A. Vardi
Starting with a Gaussian variational ansatz, we predict anisotropic bright solitons in quasi-2D Bose-Einstein condensates consisting of atoms with dipole moments polarized \emph{pe…
Confinement effects on the stimulated dissociation of molecular BECs
I. Tikhonenkov, A. Vardi
We show that a molecular BEC in a trap is stabilized against stimulated dissociation if the trap size is smaller than the resonance healing length . Th…
Quantum dynamics of Bose-Hubbard Hamiltonians beyond Hartree-Fock-Bogoliubov: The Bogoliubov backreaction approximation
I. Tikhonenkov, J. R. Anglin, A. Vardi
e formulate a method for studying the quantum field dynamics of ultracold Bose gases confined within optical lattice potentials, within the lowest Bloch-band Bose-Hubbard model. Ou…
