Blackbody radiation shift in a 43Ca+ ion optical frequency standard
Bindiya Arora, M. S. Safronova, Charles W. Clark
Motivated by the prospect of an optical frequency standard based on 43Ca+, we calculate the blackbody radiation (BBR) shift of the 4s_1/2-3d_5/2 clock transition, which is a major…

Landau damping: instability mechanism of superfluid Bose gases moving in optical lattices
Kiyohito Iigaya, Satoru Konabe, Ippei Danshita +1
We investigate Landau damping of Bogoliubov excitations in a dilute Bose gas moving in an optical lattice at finite temperatures. Using a 1D tight-binding model, we explicitly obta…
