Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Leptogenesis in supersymmetry with one L violating coupling
European Physical Journal C: Particles and Fields, 2021 We have shown a new scenario of successful leptogenesis with one L violating coupling and a relative Majorana phase playing the role of CP violation.

Multiloop String-Like Formulas for QED
, 1992 Multiloop gauge-theory amplitudes written in the Feynman-parameter representation are poised to take advantage of two important developments of the last decade: the spinor-helicity technique and the superstring reorganization.

Validity of Feynman's prescription of disregarding the Pauli principle in intermediate states [PDF]
, 1998 Regarding the Pauli principle in quantum field theory and in many-body quantum mechanics, Feynman advocated that Pauli's exclusion principle can be completely ignored in intermediate states of perturbation theory.

Advanced Science, EarlyView.Valence‐engineering of CeO2 redox modulator can remove the highly oxidative by‐products and accelerate the oxidation state transitions of Co/Fe centers in FeCo dual‐atom catalyst during oxygen reduction/evolution electrocatalysis. Therefore, the stability and activity issues are resolved, significantly enhancing the overall performance when used as an ...

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Integration-by-parts identities and differential equations for parametrised Feynman integrals
Journal of High Energy PhysicsIntegration-by-parts (IBP) identities and differential equations are the primary modern tools for the evaluation of high-order Feynman integrals. They are commonly derived and implemented in the momentum-space representation.
