Dissipative electrically driven fluids

open access: yesJournal of High Energy Physics
We consider entropy generating flows for fluids that achieve a steady state in the presence of a driving electric field. Having chosen one among the space of stationarity constraints that define such flows we show how energy and momentum relaxation are ...

Notes on resonances and unitarity from celestial amplitudes

open access: yesJournal of High Energy Physics, 2022
We study the celestial description of the O(N) sigma model in the large N limit as introduced by Coleman, Jackiw and Politzer. Focusing on three dimensions, we analyze the implications of a UV complete, all-loop order 4-point amplitude of pions in terms ...

Iridium Oxide Inverse Opal Anodes with Tailored Porosity for Efficient PEM Electrolysis

open access: yesAdvanced Functional Materials, Volume 35, Issue 42, October 15, 2025.
The synthesis of Iridium‐based Inverse Opals (Ir‐IO) is reported as electrocatalyst for Proton exchange membrane water electrolysis (PEM‐WE). Using the developed protocol it produces highly porous materials consisting either of metallic, oxidic Iridium or a combination thereof with large surface areas.

Three-point functions from a Schwinger-Keldysh effective action, resummed in derivatives

open access: yesJournal of High Energy Physics
The search for the conjectured QCD critical point in heavy-ion collisions requires to account for far-from equilibrium effects as well as fluctuations, and in particular non-Gaussian fluctuations, in the modeling of the dynamics of the hot and dense ...

Reduction of topological invariants on null hypersurfaces

open access: yesJournal of High Energy Physics
Gravitational helicity flux density represents the angular distribution of helicity flux in general relativity. In this work, we explore its relationship to the reduction of topological invariants at future null infinity. Contrary to initial expectations,
