Quantum Chaos of Bogoliubov Waves for a Bose-Einstein Condensate in Stadium Billiards
Chuanwei Zhang, Jie Liu, Mark G. Raizen +1
We investigate the possibility of quantum (or wave) chaos for the Bogoliubov excitations of a Bose-Einstein condensate in billiards. Because of the mean field interaction in the co…
Dynamical generation of two-dimensional matter-wave discrete solitons
Artem M. Dudarev, Roberto B. Diener, Qian Niu
We suggest a method to experimentally obtain two-dimensional matter-wave discrete solitons with a {\it self-repulsive} BEC in optical lattices. At the edge of the Brillouin zone, a…
Spin-orbit coupling and Berry phase with ultracold atoms in 2D optical lattices
Artem M. Dudarev, Roberto B. Diener, Iacopo Carusotto +1
We show how spin-orbit coupling and Berry phase can appear in two-dimensional optical lattices by coupling atoms' internal degrees of freedom to radiation. The Rashba Hamiltonian,…
Interaction broadening of Wannier functions and Mott transitions in atomic BEC
Jinbin Li, Yue Yu, Artem M. Dudarev +1
Superfluid to Mott-insulator transitions in atomic BEC in optical lattices are investigated for the case of number of atoms per site larger than one. To account for mean field repu…
Superfluidity of Bose-Einstein Condensate in An Optical Lattice: Landau-Zener Tunneling and Dynamical Instability
Biao Wu, Qian Niu
Superflow of Bose-Einstein condensate in an optical lattice is represented by a Bloch wave, a plane wave with periodic modulation of the amplitude. We review the theoretical result…
Transition to Instability in a Kicked Bose-Einstein Condensate
Chuanwei Zhang, Jie Liu, Mark G. Raizen +1
A periodically kicked ring of a Bose-Einstein condensate is considered as a nonlinear generalization of the quantum kicked rotor. For weak interactions between atoms, periodic moti…
A Quantum Tweezer for Atoms
Roberto B. Diener, Biao Wu, Mark G. Raizen +1
We propose a quantum tweezer for extracting a desired number of neutral atoms from a reservoir. A trapped Bose-Einstein condensate (BEC) is used as the reservoir, taking advantage…
Quantum Step Heights in Hysteresis Loops of Molecular Magnets
Jie Liu, Biao Wu, Li-Bin Fu +2
We present an analytical theory on the heights of the quantum steps observed in the hysteresis loops of molecular magnets. By considering the dipolar interaction between molecular…
