Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

Advanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Mirror symmetry breaking of superradiance in a dipolar Bose-Einstein condensate

Physical Review Research
Dicke superradiance occurs when two or more emitters cooperatively interact via the electromagnetic field. This collective light-scattering process has been extensively studied across various platforms, from atoms to quantum dots and organic molecules ...

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 ...

Self-organized criticality in boson clouds around black holes

, 2012
Boson clouds around black holes exhibit interesting physical phenomena through the Penrose process of superradiance, leading to black hole spin-down. Axionic clouds are of particular interest, since the axion Compton wavelength could be comparable to the

Monolayer J‐Aggregate Crystals Strong Coupling with an All‐Dielectric Metasurface for Photonic Properties Modification

Laser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
The monolayer J‐aggregate PTCDI‐C13, grown on thin hBN, is transferred to an all‐dielectric metasurface to achieve strong coupling between optical modes (GMRs and qBICs) and Frenkel excitons. With low losses in both microcavities and excitons, a Rabi splitting of 78 meV is observed in both reflectance and photoluminescence k‐space maps, enabling ...

Testing the Weak Cosmic Censorship Conjecture via Test Particle–Induced Overcharging/Overspinning of Kerr–Newman–Modified Gravity Black Hole

Advances in Astronomy, Volume 2026, Issue 1, 2026.
We examine the weak cosmic censorship conjecture (WCCC) violation by throwing a charged and rotating test particle into a Kerr–Newman–modified gravity black hole (KN–MOG BH). The result depends on several factors, such as the relative sign of the particle’s charge and its direction of rotation with respect to black hole (BH).

Intensity fluctuations in steady state superradiance

, 2010
Alkaline-earth like atoms with ultra-narrow optical transitions enable superradiance in steady state. The emitted light promises to have an unprecedented stability with a linewidth as narrow as a few millihertz.

From bound states to quantum spin models: chiral coherent dynamics in topological photonic rings

Nanophotonics, Volume 14, Issue 24, Page 4397-4409, December 2025.
Abstract Topological photonic systems offer a robust platform for guiding light in the presence of disorder, but their interplay with quantum emitters remains a frontier for realizing strongly correlated quantum states. Here, we explore a ring‐shaped Su‐Schrieffer‐Heeger (SSH) photonic lattice interfaced with multiple quantum emitters to control ...
