Many-Body Physics with Ultracold Gases
This paper reviews recent experimental and theoretical progress concerning many-body phenomena in dilute, ultracold gases. It focuses on effects beyond standard weak-coupling descriptions, such as…

Experimental Test of Bell's Inequalities Using Time- Varying Analyzers
Correlations of linear polarizations of pairs of photons have been measured with time-varying analyzers. The analyzer in each leg of the apparatus is an acousto-optical switch followed by two linear…

Laser cooling below the Doppler limit by polarization gradients: simple theoretical models
We present two cooling mechanisms that lead to temperatures well below the Doppler limit. These mechanisms are based on laser polarization gradients and work at low laser power when the…

Berezinskii–Kosterlitz–Thouless crossover in a trapped atomic gas
TLDR
The observation of a BKT-type crossover in a trapped quantum degenerate gas of rubidium atoms is reported, providing direct experimental evidence for the microscopic mechanism underlying the BKT theory, and raising new questions regarding coherence and superfluidity in mesoscopic systems.

Quantum simulations with ultracold quantum gases
Experiments with ultracold quantum gases provide a platform for creating many-body systems that can be well controlled and whose parameters can be tuned over a wide range. These properties put these…

Monte Carlo wave-function method in quantum optics
We present a wave-function approach to the study of the evolution of a small system when it is coupled to a large reservoir. Fluctuations and dissipation originate in this approach from quantum jumps…

Colloquium: Artificial gauge potentials for neutral atoms
When a neutral atom moves in a properly designed laser field, its center-of-mass motion may mimic the dynamics of a charged particle in a magnetic field, with the emergence of a Lorentz-like force.…

Periodically Driven Quantum Systems: Effective Hamiltonians and Engineered Gauge Fields
Topological effects can result from a material's intrinsic properties, or can be generated by external electromagnetic fields or mechanical deformations. Researchers analyze how driven quantum…

Two-dimensional Bose fluids: An atomic physics perspective
The properties of phase transitions and the types of order present in the low-temperature states of matter are fundamentally dependent on the dimensionality of physical systems. Generally, highly…

Stationary states of a rotating Bose-Einstein condensate: routes to vortex nucleation.
Using a focused laser beam we stir a 87Rb Bose-Einstein condensate confined in a magnetic trap. We observe that the steady states of the condensate correspond to an elliptic cloud, stationary in the…
