Homogeneous atomic ensembles and single-mode field: review of simulation results

We consider ensembles of two level atoms interacting with the field in one mode resonator; such ensembles are homogeneous, if the force of interaction is the same for all atoms. We represent the results of numerical simulation of the following effects: relaxation of atomic excitation for one atom, dephasing assisted transport of energy along the chain of optical cavities (DAT), optical conductivity of a network of cavities, quantum bottleneck, thermal attractors for two atomic systems and ensemble Rabi oscillation for a hundred of atoms and dark states. The last effect required the supercomputer simulation on Lomonosov-2. DAT and quantum bottleneck play the peculiar role in biology (FMO light harvesting complex in green sulfur bacteria), dark states are significant for quantum computations. This elucidates the special role of dark states in such ensembles and the power of finite dimension models of QED, which allow inclusion of dipole-dipole interaction and nonlinearity that makes such models very powerful.

Cavity-field-assisted atomic relaxation and suppression of resonance fluorescence at high intensities

Gautam Gangopadhyay, Samita Basu, Deb Shankar Ray

Within the framework of the cavity QED model we consider a cavity-field-assisted dissipation process via a Raman-type coupling of the atom-cavity system (under off-resonance conditions) to a reservoir. We show that at higher applied field strength the Mollow triplet gets significantly suppressed due to this cavity-field-dependent atomic relaxation.

Macroscopic QED - concepts and applications

Stefan Scheel, Stefan Yoshi Buhmann

In this article, we review the principles of macroscopic quantum electrodynamics and discuss a variety of applications of this theory to medium-assisted atom-field coupling and dispersion forces. The theory generalises the standard mode expansion of the electromagnetic fields in free space to allow for the presence of absorbing bodies. We show that macroscopic quantum electrodynamics provides the link between isolated atomic systems and magnetoelectric bodies, and serves as an important tool for the understanding of surface-assisted atomic relaxation effects and the intimately connected position-dependent energy shifts which give rise to Casimir-Polder and van der Waals forces.
