Termination of superradiance from a binary companion
, 2022 We study the impact of a binary companion on black hole superradiance at orbital frequencies away from the resonance bands of the superradiant cloud.

Superradiant Terahertz Emission by Dipolaritons [PDF]
Physical Review Letters, 2013 Dipolaritons are mixed light-matter quasiparticles formed in double quantum wells embedded in microcavities. Due to resonant coupling between direct and indirect excitons via electronic tunnelling, dipolaritons possess large dipole moments. Resonant excitation of the cavity mode by a short pulse of light induces oscillations of the indirect exciton ...

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.

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.

Generation, amplification, and nonlinear self-compression of powerful superradiance pulses
, 2012 Superradiance (SR) of electron bunches can be considered an effective method of production of ultrashort electromagnetic pulses. Different types of SR associated with different mechanisms (cyclotron, Cherenkov, and bremsstrahlung) of stimulated emission ...

Superradiant Quantum Heat Engine [PDF]
Scientific Reports, 2015 AbstractQuantum physics revolutionized classical disciplines of mechanics, statistical physics and electrodynamics. One branch of scientific knowledge however seems untouched: thermodynamics. Major motivation behind thermodynamics is to develop efficient heat engines.

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 ...
