This paper demonstrates that pure natural inflation, a top-down single-field model, is compatible with the latest Atacama Cosmology Telescope CMB constraints under both instantaneous and standard reheating scenarios, thereby validating a significant portion of its parameter space and that of its phenomenological extensions.
This paper presents a streamlined method for constructing exact black hole solutions in non-commutative gauge theory using the Seiberg-Witten map, revealing that non-commutativity resolves temperature divergences during evaporation, induces phase transitions, and suppresses particle emission correlations.
This paper demonstrates that for shift-symmetric scalars in de Sitter space, a quantum anomaly in renormalization forces the late-time wavefunction to acquire an imaginary part that is entirely determined by its renormalization scale dependence to all loop orders, thereby establishing an infinite set of relations among correlators of massless fields and their conjugate momenta.
This paper presents a full calculation of Molière scattering between jet partons and QGP quasiparticles implemented within the Hybrid Model, demonstrating that photon-tagged jets serve as a sensitive probe for detecting distinctive experimental signatures of these hard scatterings through their impact on jet substructure observables like the Soft Drop angle and jet girth.
This paper establishes a comprehensive theory of multiary graded polyadic algebras by extending classical group-graded algebras to higher-arity structures, introducing multiary group gradings, and uncovering unique phenomena such as higher power gradings and specific arity compatibility constraints through results like quantization rules and a First Isomorphism Theorem.
This paper demonstrates that the propagator of a Hawking particle in the far-horizon region of Schwarzschild spacetime, derived using quantum field theory in curved spacetime, differs from the result obtained via the path-integral formalism, thereby highlighting a theoretical discrepancy between the standard description of high-energy quantum fields in curved spacetime and the low-energy quantum mechanical phenomena observed in Earth's gravitational field.
By applying Schwinger's variational principle to the Einstein-Cartan action, the authors derive quantum commutation relations between the metric and torsion tensors.
This paper presents a general method for reconstructing the spin density matrix of multi-particle systems from angular decay data using Bloch parameterization and Wigner-Weyl transforms, and applies it to Monte Carlo simulations of massive particle decays to propose measurements for detecting entanglement and Bell inequality violations.
This paper analytically computes the capacity of entanglement in the Russo-Susskind-Thorlacius (RST) model of two-dimensional dilaton gravity, revealing that while single-interval capacity remains time-independent, the global replica backreaction induces a time-dependent capacity for two intervals that signals non-uniform saddle competition and sharp features at the Page transition.
This paper reports the quantum simulation of massive relativistic fields in 2+1 dimensions using a two-component Bose-Einstein condensate to encode the sine-Gordon model, successfully demonstrating both tunable relativistic dispersion in the perturbative regime and non-perturbative topological domain walls.
This paper conjectures analytic expressions for the non-local magic of bipartite pure qudit states with prime local dimensions, supported by numerical evidence for qutrits and ququints, while demonstrating that these expressions fail for composite dimensions and that established qubit relations between non-local magic and entanglement do not generalize to higher-dimensional systems.
This paper establishes that Riemannian manifolds admitting a connection with closed, covariantly constant torsion decompose locally into a product of a semisimple Lie group and a torsion-free manifold, a result used to simplify proofs for special geometries like KT and HKT manifolds and to fully characterize the geometry of complete, simply connected , , and compact 8-dimensional HKT manifolds under these conditions.
This paper proposes a definition of asymptotically flat spacetimes consistent with gravitational scattering and proves three antipodal matching conditions at spatial infinity, which are reformulated as asymptotic conservation laws governing tails and the breaking of peeling.
This paper presents a proper-time method to analytically construct and demonstrate the stability of secondary gravitational waves as perturbative solutions against a strong gravitational wave background in the Bianchi VI universe.
This paper derives WKB-asymptotic expressions for multipoint Virasoro conformal blocks in the comb channel on the sphere by applying the WKB method to the classical BPZ equation, validating the results against known exact solutions and AGT correspondence while demonstrating their utility for generalizing Zamolodchikov's elliptic recursion and numerically evaluating minimal string theory amplitudes.
This paper investigates the Casimir effect in rectangular cavities as a probe for Lorentz symmetry violation, demonstrating how a fixed background four-vector induces anisotropic, direction-dependent corrections to the vacuum energy while preserving the separability of field modes.
This paper presents an all-orders worldline effective action for Kerr-Newman black holes within twistor particle theory and identifies exact hidden symmetries in self-dual backgrounds.
This paper demonstrates that single scalar field theories minimally coupled to a Carrollian connection and invariant under extended Carrollian transformations, including supertranslations, cannot support propagating modes because these symmetries force the energy density to be static and the momentum density to vanish.
This paper demonstrates that pure SU(3) Yang--Mills theory on a punctured three-ball generates a finite, hadronic-scale spectral gap through a gauge-invariant quantum rotor mechanism driven by a Berry-shifted holonomy angle, thereby realizing "mass without mass" without introducing explicit mass terms or Higgs fields.
This paper presents the first and lowest-order examples of 3-regular 3-edge-colored graphs that violate large factorization in Gaussian random tensor models, contrasting with the well-established factorization behavior observed in random matrices.
