Engineering stimuli‐responsive shape‐morphing through high‐resolution 4D printing
Responsive Materials, Volume 3, Issue 4, November 2025.This review summarizes recent progress in high‐resolution 4D printing with smart materials and micro/nanoscale techniques. It covers actuation strategies, key applications, and future challenges for scalable, precise shape‐morphing systems. Abstract 4D printing extends conventional additive manufacturing (AM) by enabling dynamic shape‐morphing ...

The pseudospectra of black holes in AdS
Journal of High Energy PhysicsWe study the stability of quasinormal modes (QNMs) in electrically charged black brane spacetimes that asymptote to AdS by means of the pseudospectrum.

Notes on resonances and unitarity from celestial amplitudes
Journal 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 ...

Dissecting holographic conductivities [PDF]
, 2015 The DC thermoelectric conductivities of holographic systems in which translational symmetry is broken can be efficiently computed in terms of the near-horizon data of the dual black hole. By calculating the frequency dependent conductivities to the first

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.

Chiral magnetic waves in strongly coupled Weyl semimetals
Journal of High Energy PhysicsPropagating chiral magnetic waves (CMW) are expected to exist in chiral plasmas due to the interplay between the chiral magnetic and chiral separation effects induced by the presence of a chiral anomaly. Unfortunately, it was pointed out that, because of

Holographic Spontaneous Parity Breaking and Emergent Hall Viscosity and Angular Momentum [PDF]
, 2014 We study the spontaneous parity breaking and generating of Hall viscosity and angular momentum in holographic p+ip model, which can describe strongly-coupled chiral superfluid states in many quantum systems.

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.

Dissipative electrically driven fluids
Journal of High Energy PhysicsWe 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 ...

Fluids and vortex from constrained fluctuations around C-metric black hole
, 2017 By foliating the four-dimensional C-metric black hole spacetime, we consider a kind of initial-value-like formulation of the vacuum Einstein's equation, the holographic initial data is a double consisting of the induced metric and the Brown-York energy ...
