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 ...
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...
A Moving Magnetic Trap Decelerator: a New Source for Cold Atoms and Molecules
Moving Magnetic Trap Decelerator Source Cold Atoms Molecules
2010/11/12
We present a new source of cold paramagnetic atoms and molecules. The paramagnetic particles are cooled during the adiabatic expansion and become entrained in an intense, cold but fast supersonic bea...

2010/11/11
We argue that the Fermi-Hubbard Hamiltonian describing the physics of ultracold atoms on optical lattices in the presence of artificial non-Abelian gauge fields, is exactly equivalent to the gauge the...
