The future of quantum technologies: superfluorescence from solution-processed, tunable materials [PDF]

open access: yesNanophotonics
One of the most significant and surprising recent developments in nanocrystal studies was the observation of superfluorescence from a system of self-assembled, colloidal perovskite nanocrystals [G. Rainò, M. A. Becker, M. I. Bodnarchuk, R. F. Mahrt, M. V.

Enhancing cooperativity of molecular J-aggregates by resonantly coupled dielectric metasurfaces [PDF]

open access: yesNanophotonics
J-aggregates are supramolecular assemblies of dyes exhibiting strong absorption and fluorescence with narrow linewidths, as well as large optical nonlinearities, induced by the formation of largely delocalized molecular excitons.

Q-Ball Superradiance [PDF]

open access: yes, 2023
Q-balls are nontopological solitons that coherently rotate in field space. We show that these coherent rotations can induce superradiance for scattering waves, thanks to the fact that the scattering involves two coupled modes. Despite the conservation of

Dark photon superradiance quenched by dark matter [PDF]

open access: yes, 2022
Black-hole superradiance has been used to place very strong bounds on avariety of models of ultralight bosons such as axions, new light scalars, anddark photons.

Superradiance Lattice

open access: yesPhysical Review Letters, 2015
We show that the timed Dicke states of a collection of three-level atoms can form a tight-binding lattice in momentum space. This lattice, coined the superradiance lattice (SL), can be constructed based on electromagnetically induced transparency (EIT). For a one-dimensional SL, we need the coupling field of the EIT system to be a standing wave.

Superradiance and stability of the regularized 4D charged Einstein-Gauss-Bonnet black hole

open access: yesJournal of High Energy Physics, 2020
We investigated the superradiance and stability of the regularized 4D charged Einstein-Gauss-Bonnet black hole which is recently inspired by Glavan and Lin [Phys. Rev. Lett. 124, 081301 (2020)]. We found that the positive Gauss-Bonnet coupling constant α

Superradiance in Quantum Vacuum

open access: yesQuantum Reports, 2021
A new process associated with the nonlinear optical properties of the electromagnetic quantum vacuum is described. It corresponds to the superradiant emission of photons, resulting from the interaction of an intense laser pulse with frequency ω0 with a ...

Dicke superradiance in a magnetoplasma [PDF]

open access: yesPhysica B: Condensed Matter, 1999
We present theoretical results for superradiance, i.e. the collective coherent decay of a radiating system, in a semiconductor heterostructure under a strong quantizing magnetic field. We predict a strong peak (`Dicke-peak') in the emission intensity as a function of time, which should be observable after a short initial excitation of electrons into ...

Superabsorption of light via quantum engineering [PDF]

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.
