Direct Probe of Topological Order for Cold Atoms.
Direct Probe Topological Order Cold Atoms
2016/1/22
Cold-atom experiments in optical lattices offer a versatile platform to realize various topological quantum phases. A key challenge in those experiments is to unambiguously probe the topological order...
Goldilocks principle wrong for particle assembly: Too hot and too cold is just right（图）
cold right particle
2014/12/1
Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of New York University scientists has found. Th...

Long range transport of ultra cold atoms in a far-detuned 1D optical lattice
Long range transport ultra cold atoms far-detuned 1D optical lattice Atomic Physics
2012/4/27
We present a novel method to transport ultra cold atoms in a focused optical lattice over macroscopic distances of many Rayleigh ranges. With this method ultra cold atoms were transported over 5 cm in...
Diagrammatic pump-probe approach to coherent backscattering of laser light by cold atoms: Double scattering revisited
Diagrammatic pump-probe coherent backscattering of laser light cold atoms Double scattering revisited Atomic Physics
2012/4/20
We present a diagrammatic derivation of the coherent backscattering spectrum from two two-level atoms using the pump-probe approach, wherein the multiple scattering signal is deduced from single-atom ...

We experimentally realized storage and retrieval of an image of light in a cigar-shaped atomic cloud of Rubidium 85 using four-wave mixing (FWM) for the first time. The input signal and the generated ...
Analogy of RKKY oscillations to the heat exchange in cold atoms
Analogy RKKY oscillations the heat exchange cold atoms
2012/2/28
An oscillatory term is found in both the energy expectation and dynamics of a wave-packet in a time-varying harmonic trap and infinite potential well. They are proved to oscillate in coherence with th...
