Unphysical Structure Collapse in Quantum Mechanics Calculations With Continuum Solvation

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.
Quantum mechanics conformer searches with continuum solvation models yield preferably collapsed conformations not confirmed by sophisticated nuclear magnetic resonance (NMR) experiments. Continuum solvation force‐field and explicit solvation molecular dynamics simulations result preferably in stretched conformations, hinting on general weaknesses of ...

Bosonic near-CFT1 models from Fock-space fluxes

Journal of High Energy Physics
We construct a family of near-CFT1 models with a conserved U(1) charge, whose basic degrees of freedom are canonical bosons. The Sachdev-Ye-Kitaev (SYK) model — the first microscopic model that realizes the near-CFT1 dynamics — is based on random p-local

Quantum de Sitter Geometry

Universe
Quantum de Sitter geometry is discussed using elementary field operator algebras in Krein space quantization from an observer-independent point of view, i.e., ambient space formalism.

Light‐Induced Reactions of Small‐Membered Cyclic Carbonyl Compounds

European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.
This review highlights recent advances in the synthesis and photochemical reactivity of cyclopropenone and cyclobutenedione. These compounds undergo photolysis upon direct excitation, and in some cases, through indirect excitation by photocatalysts. The resulting photogenerated species exhibit unique reactivity profiles that are strongly influenced by ...

Exploring the Therapeutic Potential of Cannabidiol in Cutaneous Squamous Cell Carcinoma: An Integrated Computational and Experimental Study

International Journal of Quantum Chemistry, Volume 126, Issue 5, March 5, 2026.
Cannabidiol (CBD) exhibits increased reactivity, stronger CB1 receptor binding, and enhanced cytotoxicity against A431 squamous carcinoma cells compared to 5‐fluorouracil (5‐FU). Integrated DFT, molecular docking, and experimental analyses demonstrate CBD's improved stability and binding affinity, highlighting its potential as an alternative ...

In Materia Shaping of Randomness with a Standard Complementary Metal‐Oxide‐Semiconductor Transistor for Task‐Adaptive Entropy Generation

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
This study establishes a materials‐driven framework for entropy generation within standard CMOS technology. By electrically rebalancing gate‐oxide traps and Si‐channel defects in foundry‐fabricated FDSOI transistors, the work realizes in‐materia control of temporal correlation – achieving task adaptive entropy optimization for reinforcement learning ...

An Alternative Approach to Spontaneous Photon Triplets Generation

Advanced Physics Research, Volume 5, Issue 3, March 2026.
Day by day, communication and computing technologies are progressing at a lightning speed, which is particularly true of the quantum version of these technologies (QIST). Increasingly, these technologies are emerging from unusual and sometimes bewildering quantum optical effects, which are based on exotic quantum physical theories.

On energy and particle production in cosmology: the particular case of the gravitino

Journal of High Energy Physics
It is well-known that the number of particles produced in cosmology, commonly defined in the literature from the Fock space of the instantaneous hamiltonian of the canonically normalized fields, is ambiguous.

Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?

Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,
