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 FLRW cosmology in symmetric teleparallel gravity with a nonminimal dark matter coupling, demonstrating that the noncoincidence gauge enables a multi-scalar field representation where the coupling facilitates a viable matter-dominated era and late-time acceleration, with the de Sitter solution emerging as the unique future attractor for power-law theories.
This paper proposes a natural extension of Kaluza-Klein theory where a higher-dimensional Lorentzian manifold with a Cauchy horizon projects onto a lower-dimensional quotient manifold that undergoes a signature change from Lorentzian to Riemannian, effectively demonstrating a "signature change without signature change" scenario.
This paper presents a systematic pseudodifferential calculus approach for expanding operator kernels on curved backgrounds, demonstrating that their terms originate from ultraviolet or infrared regions and detailing methods to regularize infrared divergences via analytic continuation or mass terms.
This paper establishes a generalized definition of gravitational entropy as a charge associated with local boosts within the covariant phase space formalism, demonstrating that its variation along any causal observer's path is non-negative provided the matter content satisfies the strong energy condition.
This paper investigates charged black hole solutions in two-dimensional heterotic string theory using a T-duality-invariant formalism, analyzing their dual geometries, singularities, and gauge dependence while extending a non-perturbative solution to scenarios with multiple abelian fields.
This paper utilizes the shape invariance property of discrete quantum mechanics with pure imaginary shifts (idQM) to derive new difference and differential relations for continuous-variable orthogonal polynomials in the Askey scheme, demonstrating that multiplication by establishes surjective maps between their respective Hilbert spaces with shifted parameters.
This paper presents a non-perturbative lattice QCD determination of the scheme- and scale-independent low-energy constant using staggered fermion simulations, yielding a final result of that significantly improves upon previous estimates.
This paper introduces two novel numerical approaches for computing Feynman integrals by leveraging their complete monotonicity and Stieltjes properties to impose strong constraints on differential equation solutions and enable efficient rational approximations via Padé approximants, respectively.
This paper investigates horizon-brightened acceleration radiation for freely falling two-level atoms in a Bardeen regular black hole geometry, demonstrating that the excitation spectrum remains Planckian with a temperature set by the Bardeen Hawking temperature while showing that the radiation is strongly suppressed as the black hole approaches an extremal, cold remnant limit.
This paper presents an interpolating conformal algebra and its matrix representations in dimensions that bridge instant and light-front dynamics, demonstrating how the latter maximizes kinematic generators to significantly reduce the dynamical complexity of solving quantum field theories.
