Superradiance of a global monopole in Reissner–Nordström(–AdS) space-time

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In this article, the behavior of a charged and massive scalar field around a global monopole swallowed by a Reissner–Nordström–Anti-de Sitter (RN–AdS) black hole is investigated by considering the Klein–Gordon equation in this geometry. The superradiance

Observational prospects of self-interacting scalar superradiance with next-generation gravitational-wave detectors [PDF]

open access: yesClassical and quantum gravity
Current- and next-generation gravitational-wave observatories may reveal new, ultralight bosons. Through the superradiance process, these theoretical particle candidates can form clouds around astrophysical black holes and result in detectable ...

A Dicke Type Model for Equilibrium BEC Superradiance [PDF]

open access: yes, 2004
We study the effect of electromagnetic radiation on the condensate of a Bose gas. In an earlier paper we considered the problem for two simple models showing the cooperative effect between Bose-Einstein condensation and superradiance.

Heisenberg-Langevin approach to driven superradiance [PDF]

open access: yesPhysical Review A, 2023
We present an analytical approach for the study of driven Dicke superradiance based on a Heisenberg-Langevin formulation. We calculate the steady-state fluctuations of both the atomic-spin and the light-field operators.

SUPERRADIANCE OF NANOLASERS IN INFORMATION-MEASURING PROCEDURES [PDF]

open access: yesРадиофизика и электроника, 2018
Subject and purpose. The subject of the paper is superradiation of nanolasers and its process of quantum dot formation, increased concentration of nonequilibrium charge carriers, as well as physical principles of nanolasers operation with superradiation ...

Twisted Magnon Frequency Comb and Penrose Superradiance. [PDF]

open access: yesPhysical Review Letters, 2022
Quantization effects of the nonlinear magnon-vortex interaction in ferromagnetic nanodisks are studied. We show that the circular geometry twists the spin-wave fields with spiral phase dislocations carrying quantized orbital angular momentum (OAM ...

Superradiance of Strongly Interacting Dipolar Excitons in Moiré Quantum Materials. [PDF]

open access: yesPhysical Review Letters
Moiré lattices created in two-dimensional heterostructures exhibit rich many-body physics of interacting electrons and excitons and, at the same time, suggest promising optoelectronic applications.

Multidimensional super- and subradiance in waveguide quantum electrodynamics

open access: yesPhysical Review Research, 2020
We study the collective decay rates of multidimensional quantum networks in which one-dimensional waveguides form an intersecting hyperrectangular lattice, with qubits located at the lattice points.

The many faces of superradiance [PDF]

open access: yes, 1998
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
