Subradiance in dilute atomic ensembles: Role of pairs and multiple scattering
Y. A. Fofanov, I. M. Sokolov, R. Kaiser +1
We study numerically the slow (subradiant) decay of the fluorescence of motionless atoms after a weak pulsed excitation. We show that, in the linear-optics regime and for an excita…
Angular distribution of single photon superradiance in a dilute and cold atomic ensemble
A. S. Kuraptsev, I. M. Sokolov, M. D. Havey
On the basis of a quantum microscopic approach we study the dynamics of the afterglow of a dilute Gaussian atomic ensemble excited by pulsed radiation. Taking into account the vect…
A scaling law for light scattering from dense and cold atomic ensembles
I. M. Sokolov, A. S. Kuraptsev, D. V. Kupriyanov +2
We calculate the differential cross section of polarized light scattering from a cold and dense atomic ensemble. The regularities in the transformation of the cross section when in…
Dispersion of the dielectric permittivity of dense and ultracold atomic gases
Ya. A. Fofanov, A. S. Kuraptsev, I. M. Sokolov +1
On the basis of general theoretical results developed previously in JETP 112, 246 (2011) we analyze the atomic polarization created by weak monochromatic light in an optically thic…
Coherent backscattering under conditions of electromagnetically induced transparency
I. M. Sokolov, D. V. Kupriyanov, M. D. Havey
We consider the influence of a resonant control field on weak localization of light in ultracold atomic ensembles. Both steady-state and pulsed light excitation are considered. We…
Microscopic Theory of Scattering of Weak Electromagnetic Radiation by a Dense Ensemble of Ultracold Atoms
I. M. Sokolov, D. V. Kupriyanov, M. D. Havey
Based on the developed quantum microscopic theory, the interaction of weak electromagnetic radiation with dense ultracold atomic clouds is described in detail. The differential and…
