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 uses an effective field theory approach to derive the third-order post-Minkowskian conservative dynamics, specifically the scattering impulse and deflection angle, for compact binaries in a theory extending General Relativity with a scalar field coupled to the Gauss-Bonnet invariant.
This paper investigates the dynamics of test particles and accretion processes around Kerr-Bertotti-Robinson black holes, demonstrating how mass, rotation, and magnetic fields influence orbital frequencies, quasinormal modes, and the emergence of multiple quasi-periodic oscillations through complex accretion structures.
This paper presents a framework for the combinatorial quantization of 4d 2-Chern-Simons theory on a lattice by modeling extended Wilson surface operators on 2-graphs as measurable fields, demonstrating that their quantum 2-gauge symmetries form a Hopf category with a categorical quasitriangular structure known as cobraiding, thereby realizing the Baez-Dolan categorical ladder proposal.
This paper investigates out-of-time-order correlators (OTOCs) for holographic EPR pairs by computing four- and six-point functions via string worldsheet theory in AdS space, demonstrating consistency between the holographic influence functional and eikonal scattering approaches while revealing that six-point correlators exhibit a marginally longer scrambling time than four-point ones.
This paper establishes that symplectic singularities on smoothable projective symplectic varieties canonically admit torus actions (specifically -actions extending to ) by connecting Donaldson-Sun theory on local Kähler metrics with Poisson deformation theory, thereby proving that these singularities are cone vertices over contact orbifolds and settling Kaledin's conjecture in a stronger, canonical form.
This paper investigates holographic decoherence in quantum critical theories dual to Lifshitz geometries, demonstrating that finite-temperature black holes induce a constant decoherence rate while zero-temperature spacetimes exhibit power-law decay reminiscent of extremal black holes, and highlighting the crucial role of causality in the decoherence of entangled EPR pairs.
This paper investigates how localized Gaussian strain on a two-dimensional curved surface influences massless Dirac fermions by generating an attractive geometric potential and position-dependent Fermi velocity, which leads to bound states and localized Landau levels under an external magnetic field, thereby elucidating strain-induced electronic effects in materials like graphene.
This paper investigates the canonical quantization of a second-order pseudo-Hermitian field theory describing massive spin-1 bosons that transform under the representation of the restricted Lorentz Group and satisfy the Klein-Gordon equation.
This paper proposes efficient reheating mechanisms for the universe following supercooled phase transitions in theories with radiative symmetry breaking, detailing how the process depends on the symmetry breaking scale and demonstrating that such scenarios can simultaneously generate the observed dark matter abundance and primordial black holes.
Using DESI DR2, Planck, and DESY5 data, this study demonstrates that an interacting dark energy model with exponential quintessence and momentum coupling to dark matter allows for string-theory-motivated potential slopes () and favors a negative coupling branch that suppresses late-time growth, while also deriving tight upper limits on the sum of neutrino masses.
