Magic-zero wavelengths of alkali-metal atoms and their applications
Magic-zero wavelengths alkali-metal atoms application Quantum Gases
2011/8/4
Abstract: Using first-principles calculations, we identify "magic-zero" optical wavelengths, \lambda_zero, for which the ground-state frequency-dependent polarizabilities of alkali-metal atoms vanish....
An analytical model of Faraday rotation in hot alkali metal vapours
analytical model Faraday rotation hot alkali metal vapours Atomic Physics
2011/8/3
Abstract: We report a thorough investigation into the absorptive and dispersive properties of hot caesium vapour, culminating in the development of a simple analytical model for off-resonant Faraday r...
Universal ultracold collision rates for polar molecules of two alkali-metal atoms
Physical Chemistry Chemical Physics cold molecules
2011/8/29
Universal collision rate constants are calculated for ultracold collisions of two like bosonic or fermionic heteronuclear alkalimetal dimers involving the species Li, Na, K, Rb, or Cs. Universal colli...
Stroboscopic back-action evasion in a dense alkali-metal vapor
Stroboscopic alkali-metal vapor
2010/11/17
We explore experimentally quantum non-demolition (QND) measurements of atomic spin in a hot potassium vapor in the presence of spin-exchange relaxation. We demonstrate a new technique for back-action...
