Quantum noise limited interferometric measurement of atomic noise: towards spin squeezing on the Cs clock transition
Daniel Oblak, Jens K. Mikkelsen, Wolfgang Tittel +5
We investigate theoretically and experimentally a nondestructive interferometric measurement of the state population of an ensemble of laser cooled and trapped atoms. This study is…

Computer simulations of defects in perovskite KNbO3 crystals
R. I. Eglitis, E. A. Kotomin, A. V. Postnikov +3
An ab initio LMTO approach and semi-empirical quantum chemical INDO method have been used for supercell calculations of basic point defects - F-type centers and hole polarons bound…
