Models for Equilibrium BEC Superradiance
, 2004 9 pagesMotivated by recent experiments with superradiant Bose-Einstein Condensate (BEC) we consider simple microscopic models describing rigorously the interference of the two cooperative phenomena, BEC and radiation, in thermodynamic equilibrium.

Q-balls are non-topological 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.

Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.

Superradiance of aggregated thiacarbocyanine molecules [PDF]
, 1999 Emission lifetime and steady-state spectral measurements of aggregated and monomeric 3,3′-diethyl-5,5′-dichloro-9-phenylthiacarbocyanine (DDPT) in methanol and aqueous solutions at room temperature have been conducted.

Advanced Photonics Research, Volume 7, Issue 2, February 2026.This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...

Journal of High Energy PhysicsRotating primordial black holes (PBHs) in the early universe can emit particles through superradiance, a process particularly efficient when the particle’s Compton wavelength is comparable to the PBH’s gravitational radius.

Two-Atom Superradiance Including Magnetic State Degeneracy
AtomsThe radiation pattern emitted by two atoms, interacting with each other via the vacuum radiation field, has been calculated, including effects of magnetic state degeneracy for atoms with a ground state having G=0 angular momentum and an excited state ...

Superradiance on accelerated systems [PDF]
, 2022 In this work we will study the electromagnetic superradiance phenomenon on acceler- ated systems. We will briefly cover superradiance on a cylinder, which was thermodynam- ically proven by Zel'dovich.

Controllable superradiance scaling in photonic waveguide [PDF]
We investigate the superradiance of two-level target atoms (TAs) coupled to a photonic waveguide, demonstrating that the scaling of the superradiance strength can be controlled on demand by an ensemble of control atoms (CAs).

Emergent quasicrystal in fermionic superradiance
Physical Review ResearchQuasicrystal is state of matter with multiple crystalline orders, displaying a short-range density-wave order and a long-range disorder. As an exotic state lying in between crystals and Anderson insulators, its dynamical formation is little discussed ...
