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 employs an improved K-matrix algorithm to derive unitarized amplitudes in Starobinsky gravity, successfully regulating infrared divergences to confirm that a previously observed resonance is an artifact while validating the existence of a genuine scalar resonance and analyzing other potential dynamical resonances.
The paper proposes a new set of dressing factors for massive excitations in the worldsheet S-matrix of with mixed flux, which satisfy crossing and unitarity constraints and successfully reproduce existing perturbative results for any ratio of the two three-spheres' radii.
This paper demonstrates that spontaneous symmetry breaking on discrete graphs and lattices can be understood through elementary harmonic oscillator networks, where the phenomenon's existence is governed by the spectral dimension and fractional generalizations of resistance distance, revealing a broader range of geometries where continuous symmetries are suppressed by large fluctuations compared to continuous manifolds.
This paper demonstrates that anomalies in 5D superconformal field theories engineered via M-theory on non-compact geometries can be efficiently extracted directly from extra-dimensional -invariants of the asymptotic boundary, offering a streamlined alternative to traditional blowup and resolution techniques.
This paper investigates the oscillatory behavior of the Kasner exponent near the critical point of hairy black holes dual to holographic superfluids, demonstrating that a fourth-power nonlinear term with coefficient provides precise control over the inverse periodicity of these oscillations, thereby offering new insights into the dynamical structure of black hole interiors.
This study demonstrates that applying the Medium Separation Scheme (MSS) alongside Magnetic Field Independent Regularization (MFIR) to the Nambu--Jona-Lasinio model of magnetized two-flavor color superconducting quark matter eliminates unphysical oscillations and ensures positive magnetization, thereby correcting artifacts found in traditional approaches that fail to properly separate medium effects from vacuum contributions.
This paper simplifies the calculation of group character averages in a Gaussian matrix model by deriving generic sum rules that express arbitrary traces as convolutions of a single Laguerre polynomial, despite the complexities introduced by extended Laguerre polynomials in the matrix entries.
This paper investigates the rotation of the polarization plane of electromagnetic waves caused by strong, spatially varying axion fields in neutron star polar caps, deriving both perturbative and non-perturbative solutions to demonstrate that such rotation requires axion inhomogeneity and predicting that the resulting nanosecond-scale gap-filling times could be detectable with atomic clocks.
This paper employs the covariant phase space formalism to derive a consistent first law and generalized Smarr relations for stationary black holes in Einstein-Aether gravity, revealing that the total entropy comprises both gravitational and Aether contributions, which resolves apparent tensions between different thermodynamic prescriptions in the probe-mode limit.
This study utilizes tensor network calculations to demonstrate that in D lattice gauge theory, the late-time bipartite entanglement entropy remains independent of system size under both local and non-local measurements, indicating the absence of a measurement-induced phase transition in the no-click limit.
