Collective single-photon emission and energy transfer in thin-layer dielectric and plasmonic systems [PDF]
NanophotonicsWe study the collective photon decay of multiple quantum emitters embedded in a thin high-index dielectric layer such as hexagonal boron nitride (hBN), with and without a metal substrate.

Boson star superradiance [PDF]
Science China Physics, Mechanics & Astronomy, 2023 Recently, it has been realized that in some systems internal space rotation can induce energy amplification for scattered waves, similar to rotation in real space.

Superradiance in string theory [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 We perform an extensive analysis of the statistics of axion masses and interactions in compactifications of type IIB string theory, and we show that black hole superradiance excludes some regions of Calabi-Yau moduli space. Regardless of the cosmological

Superradiant Quantum Materials [PDF]
Physical Review Letters, 2019 There is currently great interest in the strong coupling between the quantized photon field of a cavity and electronic or other degrees of freedom in materials. A major goal is the creation of novel collective states entangling photons with those degrees

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

Dicke Superradiance in Ordered Arrays of Multilevel Atoms [PDF]
PRX Quantum, 2023 In inverted atomic ensembles, photon-mediated interactions give rise to Dicke superradiance, a form of many-body decay that results in a rapid release of energy as a photon burst.

Observation of blackbody radiation enhanced superradiance in ultracold Rydberg gases
New Journal of Physics, 2021 An ensemble of excited atoms can synchronize emission of light collectively in a process known as superradiance when its characteristic size is smaller than the wavelength of emitted photons.

Shielding of Penrose superradiance in optical black holes
European Physical Journal C: Particles and Fields, 2023 We investigate the effect of superradiance shielding for the analogue rotating black holes simulated by optical vortices by calculating the radial motion of massless particles in such spacetime background.

Superradiance: Axionic couplings and plasma effects [PDF]
Physical Review D, 2023 Spinning black holes can transfer a significant fraction of their energy to ultralight bosonic fields via superradiance, condensing them in a co-rotating structure or"cloud".

Coherence and superradiance from a plasma-based quasiparticle accelerator [PDF]
Nature Photonics, 2023 Coherent light sources, such as free-electron lasers, provide bright beams for studies in biology, chemistry and physics. However, increasing the brightness of these sources requires progressively larger instruments, with the largest examples, such as ...
