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…
Magnetic field-induced spectroscopy of forbidden optical transitions with application to lattice-based optical atomic clocks
A. V. Taichenachev, V. I. Yudin, C. W. Oates +3
We develop a method of spectroscopy that uses a weak static magnetic field to enable direct optical excitation of forbidden electric-dipole transitions that are otherwise prohibiti…
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 …
Coherent population trapping in quantized light field
A. V. Taichenachev, A. M. Tumaikin, V. I. Yudin
A full quantum treatment of coherent population trapping (CPT) is given for a system of resonantly coupled atoms and electromagnetic field. We develop a regular analytical method o…
Pure superposition states of atoms generated by a bichromatic elliptically polarized filed
A. V. Taichenachev, V. I. Yudin, V. L. Velichansky +1
We find specific polarizations of components of a bichromatic field, which allow one to prepare pure superposition states of atoms, using the coherent population trapping effect. T…
