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 ...

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.

Polarization control of radiation and energy flow in dipole-coupled nanorings
New Journal of Physics, 2020 Collective optical excitations in dipole-coupled nanorings of sub-wavelength spaced quantum emitters exhibit extreme sub-radiance and field confinement facilitating an efficient and low-loss ring-to-ring energy transfer.

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

Optimization of photon storage fidelity in ordered atomic arrays
New Journal of Physics, 2018 A major application for atomic ensembles consists of a quantum memory for light, in which an optical state can be reversibly converted to a collective atomic excitation on demand. There exists a well-known fundamental bound on the storage error, when the
