Ultracold atoms point toward magnetic behavior
2017/10/25
The researchers found that applying a strong magnetic field to these ultracold atoms caused them to line up in an alternating pattern and lean away from each other. The behavior, which researchers cal...
On-site number statistics of ultracold lattice bosons
Fluctuations in optical lattice boson system monte carlo simulation and natural gas
2014/12/20
We study on-site occupation number fluctuations in a system of interacting bosons in an optical lattice. The ground-state distribution is obtained analytically in the limiting cases of strong and weak...

Landau quantization effects ultracold atom-ion
2011/9/15
We study ultracold atom-ion collisions in the presence of an external magnetic field. At low collision energy the field can drastically modify the translational motion of the ion, which follows quanti...

Tunable Superfluidity Quantum Magnetism Ultracold Polar Molecules
2011/9/13
By selecting two dressed rotational states of ultracold polar molecules in an optical lattice, we obtain a highly tunable generalization of the t-J model, which we refer to as the t-J-V -W model. In a...

2011/9/9
We investigate the resonantly enhanced tunneling dynamics of ultracold bosons loaded on a tilted 1-D optical lattice, which can be used to simulate a chain of Ising spins and associated quantum phase ...
Propagation of the relativistic charged particle in an ultracold atomic gas with Bose-Einstein condensates
Bose-Einstein condensation relativistic charged particles energy losses
2010/11/25
We study theoretically some effects caused by a propagation of the charged particle in a dilute gas of alkali-metal atoms in the state with Bose-Einstein condensates. The energy change of the high-spe...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions
2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
Population imbalance and pairing in the BCS-BEC crossover of three-component ultracold fermions
Population imbalance three-component ultracold fermions
2010/11/17
We investigate the phase diagram and the BCS-BEC crossover of a homogeneous three-component
ultracold Fermi gas with a U(3) invariant attractive interaction. We show that the system at
sufficiently ...
Interference of parametrically driven one dimensional ultracold gases
parametrically driven dimensional ultracold gases
2010/10/27
We theoretically analyze interference patterns of parametrically driven one dimensional ultracold atomic gases. By modulating the interaction strength periodically in time, we propose to excite collec...
Everlasting Quantum Wave: NIST Physicists Predict New Form of Soliton in Ultracold Gases（图）
Quantum Wave NIST Physicists Predict Soliton Ultracold Gases
2009/12/23
Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but theoreticians at the Joint ...
Physicists in Italy have shown how to transfer entropy from one ultracold gas to another using a laser beam. They say that the resulting low-entropy gas could be the ideal system for investigating qua...
