Self‐Sustained Oscillations in MoS2 Optomechanical Resonators for VHF Optical Radio

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work demonstrates the use of 2D materials drum resonators to generate and modulate radio‐over‐laser signals. Taking advantage of the self‐sustained oscillations arising in cavity optomechanical systems by a continuous wave visible laser, a radio frequency signal is generated and frequency‐modulated by just changing a DC gate voltage.

Magnetic and Optical Bistability in Tetrairon(III) Single Molecule Magnets Functionalized with Azobenzene Groups

, 2012
Tetrairon(III) complexes known as “ferric stars” have been functionalized with azobenzene groups to investigate the effect of light-induced trans–cis isomerization on single-molecule magnet (SMM) behaviour.

Tunable Broadband Transparency of Macroscopic Quantum Superconducting Metamaterials

Physical Review X, 2015
Narrow-band invisibility in an otherwise opaque medium has been achieved by electromagnetically induced transparency (EIT) in atomic systems. The quantum EIT behavior can be classically mimicked by specially engineered metamaterials via carefully ...

Diffusion–Model–Driven Discovery of Ferroelectrics for Photocurrent Applications

Advanced Science, Volume 13, Issue 31, 4 June 2026.
We developed a diffusion model–based generative AI and high‐throughput screening framework that accelerates the discovery of photovoltaic ferroelectrics. By coupling AI driven crystal generation with machine learning and DFT screening, we identified Ca3P2 and LiCdP as new ferroelectric materials exhibiting strong polarization, feasible switching ...

Discriminating ferrotoroidic from antiferrotoroidic ground states using a 3d quantum spin sensor

npj Quantum Materials
Molecular toroidal states have come to the forefront as candidates for next-generation quantum information devices owing to their bistability and protection from weak, short-range magnetic interactions. The protection offered by these non-magnetic vortex

Scanning Tunnelling Microscopy Study of Spin Interactions in Transition‐Metal Phthalocyanine Adsorbates: Mechanisms, Signatures, and Control Strategies

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Transition‐metal phthalocyanine (TMPc) molecules serve as model systems for probing the spin interactions. This review summarizes recent scanning tunnelling microscopy advances on the spin‐related phenomena in TMPc adsorbates, including Kondo effect, spin excitations, and Yu–Shiba–Rusinov states, emphasizing the mechanisms and control strategies, and ...

Effect of Coulomb interaction on nonlinear (intensity-dependent) optical processes and intrinsic bistability in a quantum well under the electric and magnetic fields

, 2011
The effect of the electrostatic Coulomb interaction on the line shape related to the intensity-dependent intersubband optical processes in a Si delta-doped quantum well is studied using the density matrix formalism.

Memristive Physical Reservoir Computing

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Memristors’ nonlinear dynamics and input‐dependent memory effects make them ideal candidates for high‐performance physical reservoir computing (RC). Based on their conductance modulation, memristors can be classified as electronic or optoelectronic types.
