Dissipative electrically driven fluids

Journal 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 ...

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

Journal 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 ...

One‐dimensional Carrollian fluids II: C1$C^1$ blow‐up criteria

Journal of the London Mathematical Society, Volume 112, Issue 5, November 2025.
Abstract The Carrollian fluid equations arise from the equations for relativistic fluids in the limit as the speed of light vanishes, and have recently experienced a surge of interest in the theoretical physics community in the context of asymptotic symmetries and flat‐space holography.

Reduction of topological invariants on null hypersurfaces

Journal 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,

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

Advanced 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.

Holographic Rényi n → 0 entropy and Euclidean fluids

Journal of High Energy Physics
We explore the holographic prescription for computing the refined Rényi entropies S ~ n $$ {\overset{\sim }{S}}_n $$ in the n → 0 limit within the AdS d+1/CFT d framework.

Duality symmetry and dynamics on finite null boundaries

Journal of High Energy Physics
In this work, we derive a set of boost-weighted w functionals of the metric, with w ∈ {2, 1, 0, –1, –2}, which transform semi-covariantly under the action of the near-horizon symmetry group.
