Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.
At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.
Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.
This paper demonstrates that identical topological manifolds, specifically the 7-sphere endowed with inequivalent differential structures, can support distinct physical laws, as evidenced by explicit variations in the Dirac operator spectrum under a Kaluza-Klein reduction to SO(4) Yang-Mills gauge theory.
This paper utilizes the EFT of inflation in the decoupling limit to derive a non-perturbative Hamiltonian for single-field ultra slow-roll (USR) inflation, revealing that instantaneous transitions to the slow-roll phase cause higher-order loop corrections on long CMB scales to grow rapidly, potentially pushing the model out of perturbative control.
This paper derives all-order interaction Hamiltonians and non-linear field relations for single-field inflation with a transient ultra-slow-roll phase, demonstrating that loop corrections to long-wavelength perturbations grow rapidly as , thereby causing a breakdown of perturbative control at the fourth loop order in standard models used for primordial black hole formation.
This paper derives functional renormalization group flow equations for antisymmetric rank-2 tensor field models at finite temperature, specifically analyzing symmetry breaking patterns such as and to gain insights into their scale-dependent behavior and phase transitions.
This paper investigates the spherically symmetric gravitational collapse of diverse matter fields in de Sitter spacetime by combining analytical and numerical methods to demonstrate that the quasilocal formalism of marginally trapped surfaces effectively tracks the evolution of black hole and cosmological horizons.
This paper argues that while the Thermofield-Double (TFD) interpretation of the Minkowski vacuum is a useful calculational tool for capturing thermal features, it is not an exact description of the vacuum's Hilbert space structure, as evidenced by systematic mismatches in higher-derivative correlators and the fact that TFD-like forms can be artificially generated through alternative coordinate choices.
This paper presents the first numerical construction of asymptotically flat, electrically charged, rotating black hole solutions in Einstein-Maxwell-dilaton theory for arbitrary dilaton coupling constants, revealing new features such as potential non-uniqueness for specific coupling ranges where analytical solutions were previously unavailable.
This paper applies the background charged bosonic free-field approach and Coulomb-gas formalism to construct Ishibashi states and derive analytical expressions for disk two-point correlation functions in rational principal quantum Drinfeld-Sokolov minimal models with boundaries, utilizing Fock space resolutions, Pochhammer contour integrals, and Lauricella's hypergeometric functions.
This paper demonstrates that the Nambu-Goto string emerging from three-dimensional gravitational junctions is holographically dual to conformal interfaces that realize tunable energy transmitters via quantum maps factorized into scattering matrices and Virasoro algebra automorphisms.
This paper establishes sharp constraints on the parameters of the Drude-Kadanoff-Martin model by deriving upper bounds on the charge density retarded Green's function, demonstrating that the model fails at microscopic scales and proving a Mott-Ioffe-Regel-type bound that forbids conventional Drude peaks in systems where the collective mean free path is significantly shorter than the lattice spacing.
