Revealing the superfluid–Mott-insulator transition in an optical lattice
Numerical solution of single particle the density matrix ultracold atomic optical lattice parabola mott insulator
2014/12/22
We study (by an exact numerical scheme) the single-particle density matrix of ～103 ultracold atoms in an optical lattice with a parabolic confining potential. Our simulation is directly relevant to th...
Commensurate Two-Component Bosons in an Optical Lattice: Ground State Phase Diagram
Bosons optical lattice superfluid quantum systems and quantum
2014/12/20
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating ground states with rich and nontrivial phase diagram. The structure of the grou...

Ultracold atoms optical lattice quantum gas the diffraction optics
2014/12/19
We analyze the interference pattern produced by ultracold atoms released from an optical lattice, commonly interpreted as the momentum distributions of the trapped quantum gas. We show that for finite...

Non-adiabatic transitions non-symmetric optical lattice
2011/7/27
Abstract: We study Landau-Zener interband transitions for a non-symmetric optical lattice in the presence of an external force. We show that gain and losses of the light beam, as well as the relative ...

Analysis of the near-resonant fluorescence spectra of a single rubidium atom localized in a three-dimensional optical lattice
Analysis single rubidium atom localized three-dimensional optical lattice
2010/11/9
Supplementary information is presented on the recent work by W. Kim et al. on the matter-wave-tunneling-induced broadening in the near-resonant spectra of a single rubidium atom localized in a three-...
Quantum dynamics of instability-induced pulsations of a Bose-Einstein condensate in an optical lattice
Quantum dynamics instability-induced pulsations Bose-Einstein condensate optical lattice
2010/4/13
We study the dynamics of a Bose-Einstein condensate in a one-dimensional optical lattice in the limit of weak atom-atom interactions, including an approximate model for quantum fluctuations. A pulsati...

Quantum and Classical Dynamics BEC Large-Period Optical Lattice
2010/4/8
We experimentally investigate diffraction of a Rb-87 Bose-Einstein condensate from a 1D optical lattice. We use a range of lattice periods and timescales, including those beyond the Raman-Nath limit. ...
