Wigner negativity, random matrices and gravity

Journal of High Energy Physics
Given a choice of an ordered, orthonormal basis for a D-dimensional Hilbert space, one can define a discrete version of the Wigner function — a quasi-probability distribution which represents any quantum state as a real, normalized function on a discrete

Quantum Field Theory in the Weyl–Wigner Representation

Universe
The Wigner representation for quantum mechanics of particles is generalized to Bose fields. The standard Hilbert space quantization becomes, via the Weyl transform, a quantization method that consists of adding a Gaussian zeropoint field distribution to ...

Concentrated Solar Combined With Hydrothermal Treatment to Unlock Lignin Graphitization Mechanisms

Global Challenges, Volume 10, Issue 7, July 2026.
Advanced carbon materials such as graphitic biocarbons are successfully obtained from kraft lignin. A sustainable production route is highlighted using a combination of hydrothermal carbonization and solar carbonization, leading to the production of long and well‐stacked graphene layers in the biocarbon.

Recent Advances in Photonic Bound States in the Continuum: From Fundamentals to Engineering and Implementation

Laser &Photonics Reviews, Volume 20, Issue 13, 8 July 2026.
This review summarizes recent progress in meta‐photonics with a focus on bound states in the continuum (BICs) as a powerful platform for light confinement and control. It covers fundamental concepts, design strategies across optical regimes, symmetry breaking for practical quasi‐BICs, tunable and AI‐assisted BIC devices, and emerging applications in ...

Computing the Molecular Ground State Energy in a Restricted Active Space Using Quantum Annealing

Advanced Quantum Technologies, Volume 9, Issue 7, July 2026.
Can modern quantum annealers tackle realistic molecular problems? By combining XBK Hamiltonian mappings, next‐generation D‐Wave hardware, and advanced annealing protocols, significantly larger molecular instances become accessible with improved energy accuracy.
