Cooperative emission in quantum plasmonic superradiance
, 2019 International audiencePlasmonic superradiance originates from the plasmon mediated strong correlation that builds up between dipolar emitters coupled to a metal nanoparticle.

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.

Phonon Engineering in Ultrathin Sn Films
Advanced Materials Interfaces, Volume 13, Issue 8, 21 April 2026.When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Energy extraction from AdS black holes via superradiance
Journal of High Energy Physics, 2022 Superradiance is known as a wave amplification process caused by rotating or charged black holes. We argue that the superradiance of stationary black holes in asymptotically AdS spacetimes can be characterized by the ability of energy extraction ...

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, Volume 20, Issue 8, 17 April 2026.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Dirac Clouds around Dilatonic Black Holes
Research, 2022 Dirac cloud is in absence in general relativity since the superradiance mechanism fails to work for Dirac fields. For the first time, we find a novel mechanism to support Dirac clouds, which is independent on superradiance mechanism.

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics
Nanophotonics, Volume 15, Issue 5, 16 March 2026.Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly

Superradiance paradox in waveguide lattices
, 2020 Recently, it has been suggested that the collective radiative decay of two point-like quantum emitters coupled to a waveguide, separated by a distance comparable to the coherence length of a spontaneously emitted photon, leads to an apparent ...
