Covariant Locally Localized Gravity and vDVZ Continuity

Hao Geng, Moritz Merz, Lisa Randall · 2026

The Karch-Randall braneworld concerns the physics of an AdS$_{d}$ brane embedded in an ambient gravitational AdS$_{d+1}$ spacetime. The gravitational theory induced on the AdS$_{d}$ brane has a very l…

Giant Spin Magnetization from Quantum Geometry in Altermagnets

Neelanjan Chakraborti, Sudeep Kumar Ghosh, Snehasish Nandy · 2026

Altermagnets host spin-split band structures while exhibiting vanishing equilibrium spin magnetization, making field-induced responses a direct probe of their quantum geometry. A central question, in …

Deep Strong light-matter Coupling in 3D Kane Fermions

Dmitriy Yavorskiy, David Hagenmuller, Noureddine Charrouj, Yurii Ivonyak, Alexander Kazakov, Yanko Todorov, Wojciech Knap, Marcin Bialek · 2026

Deep strong light-matter coupling represents an extreme non-perturbative regime of quantum electrodynamics, in which the interaction strength exceeds the bare frequencies of the uncoupled systems. The…

Order by disorder up to arbitrarily high temperature

Ravish Mehta · 2026

We prove that a class of classical lattice models on $\mathbb{Z}^d$ ($d \geq 2$) with on-site space $\mathbb{N}_0$ exhibits long-range checkerboard order at sufficiently high temperature. The model ha…

Chiral Symmetry and Its Restoration in QCD

Teiji Kunihiro · 2026

Starting with describing the Dirac equation in an unconventional manner, we introduce the notion of chirality and show how chiralities are mixed in the massive Dirac particles.Then we discuss the appr…

Axion dark matter from extended misalignment with a constant-$\omega_\phi$ pre-oscillatory phase and dark radiation

Jose Maria Perez-Poyatos · 2026

In this work, we extend the standard pre-inflationary misalignment mechanism for axion-like particles (ALPs) by introducing a pre-oscillatory phase with constant equation of state $\omega_\phi\in[-1,1…

Couch-Torrence conformal inversion, supersymmetry and conserved charges for D3-branes

Mohammad Akhond, Massimo Bianchi, Antonio Cristofaro, Fabio Riccioni · 2026

An asymptotically flat spacetime in $D=4$ can be mapped via Couch-Torrence conformal inversion to the geometry around an extremal non-expanding and non-rotating horizon. At the linearized level, an in…

Cosmological Tensions as Consistency Conditions for f(Q) Gravity

Amare Abebe · 2026

Cosmology has entered a precision era in which discrepancies between independent datasets, most notably the $H_0$ and $S_8$ tensions, have become robust and statistically significant. These tensions a…

Strangeness enhancement in pp collisions from string closepacking in Pythia 8.3

Javira Altmann, Lorenzo Bernardinis, Peter Skands, Valentina Zaccolo · 2026

Measurements at LHC show an increased production of strange hadrons with charged multiplicity in pp collisions, which is not described by the Lund String Model (with the Monash tune) implemented in PY…

Guided elastic waves for soft elastomer characterization: an alternative to conventional rheometry

Samuel Croquette, Pierre Chantelot, Daniel A. Kiefer, Claire Prada, Fabrice Lemoult · 2026

Elastic wave propagation is intrinsically sensitive to the mechanical properties of the medium through which it travels. In soft elastomers, this makes guided elastic waves natural probes of viscoelas…

Observation of Universal Spectral Moments and the Dynamic Dispersive-to-Proliferative Transition

Jia-Xin Zhong, Chang Shu, Nan Cheng, Jee Woo Kim, Kai Zhang, Kai Sun, Yun Jing · 2026

In non-Hermitian systems, spectra can be maximally boundary-sensitive, yet bulk physics need not be. Here we experimentally show that spectral moments provide boundary-robust bulk observables in finit…
