Vector Cooper Pairs and Coherent-Population-Trapping-like States in Ensemble of Interacting Fermions
A. V. Taichenachev, V. I. Yudin
Using the standard Hamiltonian of the BCS theory, we show that in an ensemble of interacting fermions with the spin 1/2 there exist coherent states , which nullify the Hamilt…
Experimental Investigation of the Dark Pseudoresonance on the D1 Line of the 87Rb Atom Excited by a Linearly Polarized Field
Sergei Zibrov, V. L. Velichansky, A. S. Zibrov +2
The measurements of the metrological characteristics (amplitude, width, and shift in the magnetic field) of the dark pseudoresonance, which was proposed by Kazakov et al. [quant-ph…
Experimental preparation of pure superposition states of atoms via elliptically polarized bichromatic radiation
Sergei A. Zibrov, V. L. Velichansky, A. V. Taichenachev +2
We propose a simple and effective way of creating pure dark superposition states. The generation of pure states is carried out by using bichromatic radiation with controllable pola…
On the unique possibility to increase significantly the contrast of dark resonances on D1 line of Rb
A. V. Taichenachev, V. I. Yudin, V. L. Velichansky +1
We propose and study, theoretically and experimentally, a new scheme of excitation of a coherent population trapping resonance for D1 line of alakli atoms with nuclear spin …
