EPJ Web of Conferences, 2017 We investigate theoretically inversionless superradiance of an ensemble of three-level emitters (with Λ-scheme of operating transition), placed in a cyclic cavity.

Superradiant Quantum Phase Transition for an Exactly Solvable Two-Qubit Spin-Boson Model
Entropy, 2023 A spin-boson-like model with two interacting qubits is analysed. The model turns out to be exactly solvable since it is characterized by the exchange symmetry between the two spins.

The many faces of superradiance [PDF]
, 2015 Inertial motion superradiance, the emission of radiation by an initially unexcited system moving inertially but superluminally through a medium, has long been known. Rotational superradiance, the amplification of radiation by a rotating rigid object, was

Journal of High Energy PhysicsA bstract We investigate how superradiance affects the generation of baryon asymmetry in a universe with rotating primordial black holes, considering a scenario where a scalar boson is coupled to the heavy right-handed neutrinos.

A Mode-Selective Control in Two-Mode Superradiance from Lambda Three-Level Atoms
PhotonicsDicke superradiance, a single-mode burst of radiation emitted by an ensemble of two-level atoms, has garnered tremendous attention within the physics community.

Collectively induced many-vortices topology via rotatory Dicke quantum phase transition
New Journal of Physics, 2016 We examine the superradiance of a Bose–Einstein condensate pumped with a Laguerre–Gaussian laser of high winding number, e.g., ${\ell }=7$ . The laser beam transfers its orbital angular momentum (OAM) to the condensate at once due to the collectivity of ...

Characterizing superradiant dynamics in atomic arrays via a cumulant expansion approach
Physical Review Research, 2023 Ordered atomic arrays with subwavelength lattice spacing emit light collectively. For fully inverted atomic arrays, this results in an initial burst of radiation and a fast buildup of coherences between the atoms at initial times.

Mean-Field Description of Cooperative Scattering by Atomic Clouds
Atoms, 2023 We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by a uniform laser, including the initial build up, the ...
