TL;DR: Using the quantum collapse and revival phenomenon of a Bose-Einstein condensate in three-dimensional optical lattices, the atom number statistics on each lattice site are experimentally investigated in this article.

TL;DR: Based on the dynamic nature of 6Li and 133Cs atoms, a two-stage cooling process with two pairs of crossed beams in microgravity environment is suggested, which proposes a novel way to get ultracold fermion atoms with quantum degeneracy near pico-Kelvin.

TL;DR: In this article, a method of generating atomic density gratings by standing-wave manipulation of ultracold Bose gases was reported, which holds promise for substituting for traditional gratings in many applications.

TL;DR: A new calibration method based on multiple pulses Kapitza-Dirac diffraction that is almost one order of magnitude higher than that of the Raman-Nath diffraction method, and has a wide range of validity applicable to both shallow lattices and deep lattices is proposed.

TL;DR: A setup for the deep cooling of atoms in an optical trap by eliminating the influence of gravity using specially constructed magnetic coils is reported, which provides a lower limit of temperature and more freedoms to Bose gases with a simpler solution.
