Tunable quantum light by modulated free electrons

Nanophotonics, Volume 14, Issue 11, Page 1865-1878, June 2025.
Abstract Nonclassical states of light are fundamental in various applications, spanning quantum computation to enhanced sensing. Fast free electrons, which emit light into photonic structures through the mechanism of spontaneous emission, represent a promising platform for generating diverse types of states. Indeed, the intrinsic connection between the

Superradiant dark matter production from primordial black holes: impact of multiple modes and gravitational wave emission

Journal of High Energy Physics
Rotating 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.

Emergent quasicrystal in fermionic superradiance

Physical Review Research
Quasicrystal 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 ...

Quantum-enhanced photoprotection in neuroprotein architectures emerges from collective light-matter interactions

Frontiers in Physics
BackgroundSuperradiance is the phenomenon of many identical quantum systems absorbing and/or emitting photons collectively at a higher rate than any one system can individually.

Superradiance or Total Reflection? [PDF]

, 2014
Numerical evolution of massless scalar fields on Kerr background is studied. The initial data specifications are chosen to have compact support separated from the ergoregion and to yield nearly monochromatic incident wave packets. The initial data is also tuned to maximize the effect of superradiance.

Observation of superradiant synchrotron radiation in the terahertz region

Physical Review Special Topics. Accelerators and Beams, 2013
We report the first high-resolution measurement of superradiance, using coherent synchrotron radiation in the terahertz region from the Canadian Light Source synchrotron and a Michelson interferometer with a nominal frequency resolution of 0.000 96  cm^{-

THz Superradiance from a GaAs: ErAs Quantum Dot Array at Room Temperature

Applied Sciences, 2019
We report that an ErAs quantum-dot array in a GaAs matrix under 1550 nm pulsed excitation produces cooperative spontaneous emission—Dicke superradiance—in the terahertz frequency region at room temperature.

Hairless black hole by superradiance

Journal of High Energy Physics
We investigate the interplaying effects of black hole scalarization and superradiance in the context of the Einstein-Maxwell-scalar model, with the scalar field possessing electric charge.
