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...
Rydberg Spectroscopy in an Optical Lattice: Blackbody Thermometry for Atomic Clocks
Rydberg Spectroscopy Optical Lattice Blackbody Thermometry Atomic Clocks
2011/8/17
Abstract: We show that optical spectroscopy of Rydberg states can provide accurate {\em in situ} thermometry at room-temperature. Transitions from a metastable state to Rydberg states with principal q...
Domain Wall Fermion Lattice Simulation in Quaternion Basis
Domain Wall Fermion Lattice Simulation Quaternion Basis

In the QCD analysis, when quarks are expressed in quaternion basis, the quark and its charge
conjugate together are expressed by octonions and the octonion posesses the triality symmetry.
Gluos are ...
Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Perturbative renormalization factors O(a^2) corrections lattice 4-fermion operators improved fermion/gluon actions
2011/1/14
In this work we calculate the corrections to the amputated Green’s functions of 4-fermion
operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculations
is that they ...
The anti-quark--quark potential from Bethe-Salpeter amplitudes on lattice
anti-quark--quark potential Bethe-Salpeter amplitudes
2011/1/14
Potentials of quark–anti-quark pairs are studied from the q¯-q Nambu-Bethe-Salpeter (NBS) wave functions in quenched lattice QCD. With the use of a method which has been recently developed in the...
