Superabsorption of light via quantum engineering

open access: yes, 2014
Almost 60 years ago Dicke introduced the term superradiance to describe a signature quantum effect: N atoms can collectively emit light at a rate proportional to N-2.

Superradiant leptogenesis

open access: yesJournal of High Energy Physics
Abstract 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.

Mean-Field Description of Cooperative Scattering by Atomic Clouds

open access: yesAtoms, 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 ...

Chaotic Regime of Dicke Invertionless Super-Radiance in a High-Q Cavity

open access: yesEPJ Web of Conferences, 2015
We investigate theoretically different regimes of Dicke superradiance of an ensemble of three-level emitters (L configuration of the operating transitions) placed in a cyclic high-Q cavity.

Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

Reciprocal Quantum Electrodynamics With Bound States in the Continuum

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
Quantum electrodynamics accurately describes all known forms of modern optics and photonics regarding interactions between photons and matter. In this context, bound states in the continuum with photon confinement in momentum space are envisioned to open an exciting branch called reciprocal quantum electrodynamics. It complements the cavity counterpart

Accretion, evaporation and superradiance phase diagram of (primordial) black holes and 10−21 − 1021 eV scalar, vector, tensor fields

open access: yesPhysics Letters B
We obtain the accretion, evaporation and superradiance phase diagram of astrophysical and primordial black holes in the mass range 10−33−1011M⊙. This black hole mass range corresponds to production of 10−21−1021 eV particles for superradiance (bosons ...

Non-Markovian super-superradiance in a linear chain of up to 100 qubits

open access: yesPhysical Review Research, 2019
We study non-Markovian enhancement effects in the spontaneous emission of a collective excitation in a linear chain of up to 100 qubits coupled to a one-dimensional waveguide.

Penrose Superradiance in Nonlinear Optics

open access: yes, 2020
Particles or waves scattered from a rotating black hole can be amplified through the process of Penrose superradiance, though this cannot currently be observed in an astrophysical setting.
