Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, Volume 36, Issue 15, 19 February 2026.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Quantum fermion superradiance and vacuum ambiguities on charged black holes

Journal of High Energy Physics
Unlike a classical charged bosonic field, a classical charged fermion field on a static charged black hole does not exhibit superradiant scattering. We demonstrate that the quantum analogue of this classical process is however present.

Cosmology as a weak gravitational field and the trans-Planckian problem

Journal of High Energy Physics, 2023
At momenta much higher than the Hubble scale, the cosmological expansion can be thought of as a weak gravitational field. We consider QFT in a particularly convenient set of coordinates that makes this manifest, so that, for those high momenta, the ...

Deconstruction of the Anisotropic Magnetic Interactions from Spin‐Entangled Optical Excitations in van der Waals Antiferromagnets

Advanced Science, Volume 13, Issue 2, 9 January 2026.
A self‐consistent ab initio many‐body perturbation theory combined with locally exact dynamical mean field theory is employed to compute the sub‐bandgap electronic transitions in van der Waals antiferromagnets. The rich interplay between the magnetic ordering and spin‐entangled optical transitions, manifested as photoluminescence and absorption ...

Nonperturbative photon $q\bar{q}$ light front wave functions from a contact interaction model [PDF]

, 2023
We propose a method to calculate the $q\bar{q}$ light front wave functions (LFWFs) of photon at low-virtuality, i.e., the light front amplitude of $\gamma^*\rightarrow q\bar{q}$ at low $Q^2$, based on a light front projection approach.

Non-perturbative effects in μ → eγ

Journal of High Energy Physics, 2019
We compute the non-perturbative contribution of semileptonic tensor operators q ¯ σ μ ν q ℓ ¯ σ μ ν ℓ $$ \left(\overline{q}{\sigma}^{\mu \nu }q\right)\left(\overline{\ell}{\sigma}_{\mu \nu}\ell \right) $$ to the purely leptonic process μ → eγ and to the ...

An Overview of Scale Invariance in Proton Structure With Holographic Insights

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The concept of self‐similarity in the internal structure of the proton, rooted in scale invariance and fractal geometry, provides an intriguing framework for understanding the behavior of parton distribution functions (PDFs), particularly in the small x region probed in deep inelastic scattering (DIS).

Nonperturbative effects in polarization phenomena for B->K*+gamma and B->K+pi+gamma decays [PDF]

, 1997
Polarization characteristics of gamma-quanta, produced in decays B --> K* + gamma and B --> K + pi + gamma are studied in a general parity non-conserving framework. Polarization characteristics of gamma quanta for perturbative (i.e.
