Is it possible to detect permanent electric dipole moments using fluorescence measurements?

Abstract

We investigate the interaction of two-level atoms possessing finite permanent electric dipole moments with electromagnetic radiation. After framing the problem in a historical perspective, we solve it in the interaction picture and examine the possibility of extracting information on atomic permanent dipole moments from fluorescence measurements.

Quantum effect for an electric dipole

Gianfranco Spavieri

The behavior of a particle possessing a permanent or induced electric dipole moment and interacting with external electromagnetic fields is described. For a special configuration of the fields, a quantum effect is obtained for a moving dipole. The experimental observation of this effect is within reach of atom or molecular interferometry.

It is stated that the conjecture that the hydrogen-like atoms may have large permanent electric dipole moments is doubtable.Two kinds of experiments are suggested to check the reliability of the conjecture further.

Magnetometer based on atomic coherence and possible application to the search for P and T violating permanent electric dipole moments of atoms

Michael Fleischhauer, Marlan O. Scully

A new approach to the experimental search for P and T violating permanent electric dipole moments (EDMs) in atoms is proposed. The high dispersion of a phase coherent atomic medium at a point of electromagnetically induced transparency is used to detect linear Stark-shifts associated with an atomic EDM in a highly sensitive interferometric measurement. Possible noise sources are analysed and estimates are given for the device sensitivity.

Decoupling light and matter: permanent dipole moment induced collapse of Rabi oscillations

Denis G. Baranov, Mihail I. Petrov, Krasnok, Alexander E.

Rabi oscillations is a key phenomenon among the variety of quantum optical effects that manifests itself in the periodic oscillations of a two-level system between the ground and excited states when interacting with electromagnetic field. Commonly, the rate of these oscillations scales proportionally with the magnitude of the electric field probed by the two-level system. Here, we investigate the interaction of light with a two-level quantum emitter possessing permanent dipole moments. The semi-classical approach to this problem predicts slowing down and even full suppression of Rabi oscillations due to asymmetry in diagonal components of the dipole moment operator of the two-level system. We consider behavior of the system in the fully quantized picture and establish the analytical condition of Rabi oscillations collapse. These results for the first time emphasize the behavior of two-level systems with permanent dipole moments in the few photon regime, and suggest observation of novel quantum optical effects.

Electric dipole interaction in quantum optics

L. Mandeļ

It is pointed out that the electromagnetic interaction $\ensuremath{-}\stackrel{^}{\ensuremath{\mu}}\ifmmode\cdot\else\textperiodcentered\fi{}\stackrel{^}{E}$ between an atom and a field, in which the atom is modelled as a point dipole of moment $\stackrel{^}{\ensuremath{\mu}}$ interacting with the electric field $\stackrel{^}{E}$, is not strictly consistent with both quantum mechanics and Maxwell's equations. Quantum mechanics allows magnetic point dipoles but not electric point dipoles.
