We show that spontaneous Raman scattering of incident radiation can be observed in cavity-
QED systems without external enhancement or coupling to any vibrational degree of …

The paper considers the problem of collective decision-making as a second order phase-
transition, which occurs in heterogeneous information-oriented communities possessing …

We present a proposal for a tunable source of single photons operating in the terahertz
(THz) regime. This scheme transforms incident visible photons into quantum THz radiation …

The dressed atom approach provides a tool to investigate the dynamics of an atom-laser
system by fully retaining the quantum nature of the coherent mode. In its standard derivation …

The Rabi Hamiltonian, describing the interaction between a two-level atomic system and a
single-cavity mode of the electromagnetic field, is one of the fundamental models in …

Fluorescent light emission from atomic quantum systems routinely occurs at the illumination
frequency. If the system is polar, an additional fluorescence peak appears at a much lower …

Semiconductor microcavities can exhibit various macroscopic quantum phenomena,
including Bose-Einstein condensation of polaritons, Bardeen-Cooper-Schrieffer (BCS) …

In the present work we propose a novel, to the best of our knowledge, quantum material
concept, which enables superstrong and/or ultrastrong interaction of two-level systems with …

We demonstrate the robustness of the recently established Floquet-assisted superradiant
phase (FSP) of the coherently driven dissipative Dicke model, inspired by light-induced …

The emission linewidth in active medium emerges due to homogeneous and
inhomogeneous broadening. We demonstrate that in lasers with inhomogeneous …
