Mid‐Infrared Free‐Space Optical Communications: Technologies, Demonstrations and Future Directions

open access: yesIET Optoelectronics, Volume 20, Issue 1, January/December 2026.
Free‐space optical (FSO) communication is increasingly extending beyond the near‐infrared to the mid‐wave infrared (MWIR) and long‐wave infrared (LWIR) regions, which offer reduced turbulence, scattering and absorption for more robust links. This review summarises recent advances in MWIR/LWIR FSO technologies, including quantum cascade lasers, lithium ...

Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Results and techniques for higher order calculations within the gradient-flow formalism

open access: yesJournal of High Energy Physics, 2019
We describe in detail the implementation of a systematic perturbative approach to observables in the QCD gradient-flow formalism. This includes a collection of all relevant Feynman rules of the five-dimensional field theory and the composite operators ...

PHENOMENOLOGY FROM LATTICE QCD [PDF]

open access: yesLepton-Photon 01, 2002
I review two subject in which lattice simulations are making, or can make in the future, a significant contribution to particle physics phenomenology. The first subject is the evaluation of quantities which enter into the determination of the vertex A of the unitarity triangle from experimental measurements of decay rates and mixing amplitudes.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 12, December 2025.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Infrared Photovoltaic–Battery Hybrid Systems Enabled by Colloidal Quantum Dots

open access: yesChemistry – An Asian Journal, Volume 20, Issue 21, November 3, 2025.
Photovoltaic–battery (PV/B) hybrid systems are key for sustainable energy but face cost and efficiency limits. Colloidal quantum dots (CQDs) enable low‐cost near‐infrared light harvesting, surpassing silicon and III–V PVs. This review analyzes CQD properties, their roles in NIR PVs and batteries, and synthesizes current research to highlight progress ...
