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,

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 ...

Viscoelastic hydrodynamics and holography

, 2018
We formulate the theory of nonlinear viscoelastic hydrodynamics of anisotropic crystals in terms of dynamical Goldstone scalars of spontaneously broken translational symmetries, under the assumption of homogeneous lattices and absence of plastic deformations. We reformulate classical elasticity effective field theory using surface calculus in which the

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.

Superradiance in the bulk protects quantum state evolution of rapidly rotating matter on the boundary

Journal of High Energy Physics
It has been argued that the rate at which the interior of an AdS black hole evolves is dual to the rate of evolution of the (quantum state of the) strongly coupled matter on the boundary which, according to holography, is dual to the black hole. However,

Causal theories of relativistic hydrodynamics [PDF]

The first-order textbook formulations of relativistic viscous hydrodynamics are unstable and acausal. These shortcomings may be rectified by using effective theories which maintain stability and causality.

New theories of relativistic hydrodynamics in the LHC era [PDF]

, 2018
The success of relativistic hydrodynamics as an essential part of the phenomenological description of heavy-ion collisions at RHIC and the LHC has motivated a significant body of theoretical work concerning its fundamental aspects.

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.

Phase Transitions, Inhomogeneous Horizons and Second-Order Hydrodynamics [PDF]

, 2017
We use holography to study the spinodal instability of a four-dimensional, strongly-coupled gauge theory with a first-order thermal phase transition. We place the theory on a cylinder in a set of homogeneous, unstable initial states.
