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 investigates the minimum speed limit required for particles to enable the reconstruction of a potential via an inverse scattering problem, utilizing both theoretical examples and a machine learning pipeline to generalize the traditional Radon transform approach.
This paper proposes a novel method for exactly evaluating the vacuum amplitude of a single scalar field with an arbitrary potential on a lattice in any dimension by symmetrizing the kinetic exponential factor over all site permutations and applying Waring decomposition.
This paper constructs four families of single-variable spacetime metrics for a broad class of D-dimensional gravitational theories coupled to scalar and Abelian gauge fields, demonstrating their application to specific supergravity models where the scalar manifold geometry dictates the structure of the resulting solutions.
This paper derives a family of 3d abelian gauge theories from punctured lens spaces that realize unitary members of the Galois orbit of modular tensor categories and conjectures self-mirror rank-0 fixed points based on the lens space's amphichirality, extending the Gang-Kim-Stubbs framework for 3d rank-0 SCFTs.
This paper generalizes previous holographic findings on the frame-dependency of confinement temperature in rotating quark-gluon plasma by employing the most general Myers-Perry black hole solution, revealing that breaking spherical symmetry leads to a complex, non-monotonic angular dependence of the local temperature measured by a co-rotating observer.
This paper investigates the thermodynamic properties of an AdS Euler-Heisenberg black hole within the Einstein-Euler-Heisenberg framework, demonstrating that incorporating quantum thermal fluctuations via logarithmic and inverse-area entropy corrections fundamentally restructures the phase space, induces second-order phase transitions, and reveals a quantum-stabilized microscopic phase followed by macroscopic instability.
This paper proposes a unified "spectral localization principle" demonstrating that the maximum entanglement harvestable by two localized detectors from a quantum field is governed solely by the localization of the field's effective spectral density, quantified by the inverse participation ratio and expressed in a closed-form solution dependent on the cavity quality factor .
This paper investigates the quadratic-order effective energy-momentum tensor of scalar cosmological perturbations during slow-roll inflation on uniform-density hypersurfaces, systematically evaluating its behavior across different wavelength regimes and comparing it with other gauges to reveal a structured gauge dependence where uniform-density and comoving slicings coincide for adiabatic super-Hubble modes while others exhibit distinct slow-roll or gradient-dominated behaviors.
This paper demonstrates that in ghost-free extended quasidilaton massive gravity without a quasidilaton kinetic term, the addition of minimal matter (such as scalar, Maxwell, or Proca fields) fails to resolve the vanishing kinetic coefficient of transverse vector perturbations on the self-accelerating branch, leaving them infinitely strongly coupled and perturbatively unhealthy.
By employing a expansion in holographic models of confining gauge theories, the authors demonstrate that the maximum supercooling in thermal confinement transitions is universally suppressed by and determined by the speed of sound in the deconfined phase, independent of specific scalar potential details.
