Photon‐Sphere Modes in Curved Optical Microcavities: A Black‐Hole Analogue Laser
Advanced Science, Volume 13, Issue 28, 18 May 2026.An optical analogue of a Schwarzschild black hole is realized using curved microcavities that preserve light‐like geodesics. A new family of laser modes confined around the photon sphere is identified alongside conventional whispering‐gallery modes. Analytical theory, numerical simulations, and experiments reveal curvature‐induced confinement, enabling

Dicke superradiance in ordered lattices: dimensionality matters
, 2021 Dicke superradiance in ordered atomic arrays is a phenomenon where atomic synchronization gives rise to a burst in photon emission. This superradiant burst only occurs if there is one -- or just a few -- dominant decay channels.

Superradiant Ensembles of Terahertz Polaritonic Meta-Atoms
IEEE Photonics Journal, 2020 We experimentally demonstrate the robustness of strong light-matter interaction in an ensemble of terahertz cavities with variable radiation loss. Each cavity in the form of a planar metallic resonator is strongly coupled to intersubband transitions of ...

From Supramolecular Order to Device Performance in Langmuir–Blodgett and Langmuir–Schaefer Films
ChemNanoMat, Volume 12, Issue 5, May 2026.This review delves into the theoretical fundamentals and key methods for the electrical and electrochemical characterization of Langmuir–Blodgett (LB) and Langmuir–Schaefer (LS) films, with a particular emphasis on the precise nanostructuring control these techniques offer. By analyzing a selection of influential studies—ranging from early foundational

Arm‐Length‐Controlled CsPbBr3 Nanocrystals for Tunable Optical and Assembly Behavior
Advanced Materials, Volume 38, Issue 23, 22 April 2026.In this work, the synthesis parameters that dictate the formation of armed CsPbBr3 nanocrystals are described, and routes enabling precise control over arm length are proposed. Direct links between morphology and optoelectronic behavior are established.

Mirror symmetry breaking of superradiance in a dipolar Bose-Einstein condensate
Physical Review ResearchDicke 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 ...
