This paper introduces a new parton-shower algorithm that exactly reproduces the dynamics of linearized effective kinetic theory to provide a first-principles description of jet thermalization in QCD plasmas, overcoming previous limitations by properly incorporating recoils, holes, quantum statistics, and merging processes.
This paper establishes the integrability of a family of SYK models with uniform -body interactions by deriving their exact spectra and demonstrating that their underlying R-matrix corresponds to that of the critical transverse-field Ising chain, thereby revealing a profound connection between quantum chaos and statistical mechanics.
This paper proposes a new definition of Horndeski theory based on closure under invertible pure disformal transformations and the inclusion of minimal Horndeski theory, which successfully recovers the standard single-field action and provides a practical framework for constructing multi-field extensions that encompass known antisymmetric structures.
This paper investigates how the decay of a secluded scalar field, specifically a dark glueball, into gravitons versus Standard Model particles is influenced by non-minimal gravitational couplings and conformal symmetry breaking, revealing that a large Higgs-gravity coupling suppresses graviton dark radiation while favoring Standard Model reheating, and subsequently derives the resulting gravitational-wave spectrum.
This study utilizes the HYDJET++ model to demonstrate that the high degree of azimuthal alignment observed in cosmic-ray experiments is also present at the level of energetic particle clusters, highlighting how clustering procedures and momentum conservation jointly shape these correlations in high-multiplicity heavy-ion collisions.
This paper introduces minimal models, including the Arithmetic Ising Model and specific gas models, to demonstrate how entropic effects can drive generic high-energy states into ordered phases, resulting in spontaneous symmetry breaking at arbitrarily high temperatures.
This paper addresses the previously unexamined issue of volume divergences in the measure for Quadratic Gravity, demonstrating that these divergences cancel in the extremal limit similar to General Relativity, while also reviewing the complexities of renormalization in curved space and the conditions under which non-invariant measures can be justified.
This paper calculates the leading-order quantum amplitude for elastic meson-kink scattering in the double-well model, revealing a resonance pole at twice the shape mode energy that corresponds to an unstable excitation whose width is expected to be determined by higher-order corrections.
This paper investigates holographic shear correlators in a strongly-coupled 3D theory at low temperatures, demonstrating that quantum-gravitational corrections from nearly-gapless Schwarzian modes increase shear viscosity and cause the ratio to dip below the semiclassical $1/4\pi$ bound at intermediate temperatures before diverging at very low temperatures.
This paper constructs the unique primary energy-momentum tensor for conformal free scalars by solving off-shell conservation and tracelessness conditions in momentum space, expressing the result as a Gegenbauer polynomial sum that truncates for integer scaling dimensions to match known results and GJMS operator computations, while extending to nonlocal cases with a two-parameter family reflecting non-unique geometric couplings.
This paper extends self-dual nonlinear electrodynamics from four to $4p\mathsf{U}(1)(2p-1)$-forms, while introducing new theories where the energy-momentum tensor trace governs the flow with respect to a duality-invariant deformation parameter.
This paper extends the Bemfica-Disconzi-Noronha-Kovtun (BDNK) first-order dissipative relativistic hydrodynamics model to include a full first-order charge current with out-of-equilibrium corrections, demonstrating that this inclusion ensures a strongly hyperbolic, causal, and stable system coupled to Einstein's equations without requiring additional frame restrictions.
This paper presents an exact analytic solution to planar QCD by quantizing internal Majorana fermions on a rigid minimal surface, which reduces the theory to a confining twistor string that successfully predicts the meson spectrum and Regge trajectories through geometric localization and Catastrophe Theory.
This paper investigates a diverse spectrum of Euclidean gravitational saddles, including wormholes and oscillatory solutions, within Einstein-Scalar-Maxwell models to identify phase transitions, demonstrate how potential flat directions are stabilized, and estimate the probabilities of various cosmological outcomes by analytically continuing these backgrounds to Lorentzian FLRW universes.
This paper proposes group entropies as a unifying framework that defines universality classes of extensive entropies for strongly correlated systems, successfully deriving consistent thermodynamic laws and demonstrating that black holes naturally exhibit negative specific heat within this formalism.
This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper establishes an explicit isomorphism between the equivariant nilpotent cohomological Hall algebra of one-dimensional sheaves on a surface resolving a Kleinian singularity and a completed positive half of the affine Yangian of the corresponding ADE Lie algebra, utilizing continuity theorems for -structures and multi-parameter Yangian definitions to characterize the algebra of cohomological Hecke operators.
This paper extends the curve integral formula for calculating colored scalar scattering amplitudes to non-orientable surfaces, such as the Möbius strip, by utilizing quasi-cluster algebras and embedding techniques, while validating the construction through superstring amplitude limits and generalizing it to higher-genus non-orientable surfaces.
The paper proves that for spherically symmetric hairy black holes satisfying the weak energy condition, the ratio of the shadow radius to the horizon radius is bounded from below by $3\sqrt{3}/2$, a limit that is saturated by the Schwarzschild black hole.
By employing a relaxed BF-BB parametrisation of 4D gravity, this paper demonstrates that the theory possesses Chern-Simons-like phase spaces and Kac-Moody algebras on codimension 2 and 3 surfaces, respectively, governed by a Maxwell gauge algebra that yields an off-shell commutative spin connection and a noncommutative corner metric.
