Dynamical instability in kicked Bose-Einstein condensates
Bose-Einstein condensates subject to short pulses (``kicks'') from standing waves of light represent a nonlinear analog of the well-known chaos paradigm, the quantum kicked rotor. Previous studies of…
Dynamical localization of interacting ultracold atomic kicked rotors

We study a system of two atomic quantum kicked rotors with hard-core interaction. This system shows different dynamical behavior depending on the value of the kick period. In particular, we find that…
Spin–orbit-coupled Bose–Einstein condensates
The engineered SO coupling in a neutral atomic Bose–Einstein condensate sets the stage for the realization of topological insulators in fermionic neutral atom systems and develops a many-body theory that provides quantitative agreement with the observed location of the transition.
Degenerate quantum gases with spin–orbit coupling: a review
- Physics, ChemistryReports on progress in physics. Physical Society
It is shown that investigating SO coupling in cold atom systems can enrich the understanding of basic phenomena such as superfluidity, provide a good platform for simulating condensed matter states such as topological superfluids and result in novel quantum systems such as SO coupled unitary Fermi gas and high spin quantum gases.
Quantum localization for a kicked rotor with accelerator mode islands.
- PhysicsPhysical review. E, Statistical, nonlinear, and soft matter physics
It is shown here that the classical-quantum duality of the flights leads to their localization, and an analytical method and numerical procedure are developed to obtain an estimate of the localization length which has exponentially large scaling with the dimensionless Planck's constant (tilde)h<<1 in the semiclassical limit.
Bogoliubov excitations in the quasiperiodic kicked rotor: Stability of a kicked condensate and the quasi–insulator-to-metal transition
We study the dynamics of a Bose-Einstein condensate in the quasiperiodic kicked rotor described by a Gross-Pitaevskii equation with periodic boundary conditions. As the interactions are increased,…
Dynamics of the mean-field-interacting quantum kicked rotor
- PhysicsPhysical Review A
We study the dynamics of the many-body atomic kicked rotor with interactions at the mean-field level, governed by the Gross-Pitaevskii equation. We show that dynamical localization is destroyed by…
Quantum random walk of a Bose-Einstein condensate in momentum space
Each step in a quantum random walk is typically understood to have two basic components; a `coin-toss' which produces a random superposition of two states, and a displacement which moves each…
Steering random walks with kicked ultracold atoms
A kicking sequence of the atom optics kicked rotor at quantum resonance can be interpreted as a quantum random walk in momentum space. We show how to steer such a random walk by applying a random…
Realization of two-dimensional spin-orbit coupling for Bose-Einstein condensates
The realization of 2D SO coupling with advantages of small heating and topological stability opens a broad avenue in cold atoms to study exotic quantum phases, including topological superfluids.
