Gauging Non-Invertible Symmetries: Topological Interfaces and Generalized Orbifold Groupoid in 2d QFT

This paper establishes a systematic framework for gauging non-invertible symmetries in two-dimensional quantum field theories by formulating the process through topological interfaces, thereby extending standard gauging properties to general fusion categories, deriving key mathematical theorems from physical axioms, and identifying new self-dualities and a generalized orbifold groupoid structure.

Quantum field theory treatment of the neutrino spin-flavor precession in a magnetic field

This paper employs a quantum field theory framework with virtual Majorana neutrinos to derive exact dressed propagators in a magnetic field, demonstrating that the resulting spin-flavor precession probability aligns with standard quantum mechanical predictions while revealing small quantum corrections.

(2+2)D Collective Model based on a relativistic Boltzmann equation in the Isotropization Time Approximation: CoMBolt-ITA

This paper presents CoMBolt-ITA, a new (2+2)D collective model based on the relativistic Boltzmann equation in the isotropization time approximation that successfully couples pre-equilibrium dynamics with hydrodynamics to simulate quark-gluon plasma evolution, demonstrating strong consistency with standard hydrodynamic and hybrid models for small shear viscosity while revealing significant discrepancies and nontrivial thermalization effects for larger viscosity values.

Vacuum Stability Conditions for New $SU(2)$ Multiplets

This paper establishes the bounded-from-below and vacuum stability conditions for the scalar potential of the Standard Model extended by a scalar $SU(2)$ multiplet with dimension $n$ (ranging from 1 to 6), null vacuum expectation value, and arbitrary hypercharge, while also characterizing the resulting phase space geometry.

Path Integral approach to Black-hole Evaporation and Accretion

This paper presents a novel path integral methodology that unifies the study of accretion and evaporation for uncharged, non-rotating, spherically symmetric black holes in four dimensions, with a specific focus on evaporating configurations that deviate from standard thermodynamic modes.

Generation of Volume-Law Entanglement by Local-Measurement-Only Quantum Dynamics

This paper demonstrates that volume-law entanglement can be generated in a one-dimensional fermionic system without intrinsic unitary dynamics by employing a non-random, non-commuting local measurement protocol involving an auxiliary chain and detector qubits, while also showing that non-local higher-body measurements can be used to control and reduce such entanglement.

Holography for de Sitter bubble geometries

This paper generalizes de Sitter holography to geometries with a bubble of smaller or vanishing cosmological constant, proposing that the spacetime is encoded on two holographic screens when the observer's causal patch overlaps with the parent region, while requiring additional screens when they are causally disconnected.

A Light-Cone Approach to Higher-Order Cosmological Observables

This paper develops a second-order cosmological perturbation theory on a light-cone background, establishing a gauge-invariant framework that connects to the Observational Synchronous Gauge and successfully computes the luminosity distance-redshift relation up to second order while eliminating observer-position divergences in a model-independent manner.

Light scalars in light of UV/IR mixing: classicalization via synergy between Vainshtein and chameleon screenings

This paper argues that effective field theories with light scalars can achieve UV completion through classicalization, a mechanism relying on the synergy between Vainshtein and chameleon screening to generate semi-classical objects that resolve hierarchy problems via UV/IR mixing.

Topological 5d $\mathcal{N} = 2$ Gauge Theories: Mirror Symmetry and Langlands Duality of $A_\infty$ -categories of Floer Homologies

This paper establishes a physical proof of mirror symmetry and Langlands duality between specific topological 5d $\mathcal{N}=2$ gauge theories, demonstrating that the $A_\infty$ -categories of Floer homologies arising from Haydys-Witten and Geyer-Mülsch twists on certain five-manifolds are dual to each other and provide gauge-theoretic generalizations of mathematical conjectures by Bousseau and Doan-Rezchikov.
