Quantum Many-Body Culling
A. M. Dudarev, M. G. Raizen, Qian Niu
We propose a method to produce a definite number of ground-state atoms by adiabatic reduction of the depth of a potential well that confines a degenerate Bose gas with repulsive in…
Berry Phase Effects on Dynamics of Quasiparticles in a Superfluid with a Vortex
Chuanwei Zhang, Artem M. Dudarev, Qian Niu
We study quasiparticle dynamics in a Bose-Einstein condensate with a vortex by following the center of mass motion of a Bogoliubov wavepacket, and find important Berry phase effect…
Statistical Mechanics of an Optical Phase Space Compressor
Artem M. Dudarev, M. Marder, Qian Niu +2
We describe the statistical mechanics of a new method to produce very cold atoms or molecules. The method results from trapping a gas in a potential well, and sweeping through the…
Compression of Atomic Phase Space Using an Asymmetric One-Way Barrier
M. G. Raizen, A. M. Dudarev, Qian Niu +1
We show how to construct asymmetric optical barriers for atoms. These barriers can be used to compress phase space of a sample by creating a confined region in space where atoms ca…
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,…
