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 establishes a UV-finite Ryu-Takayanagi relation in AdS/CFT by utilizing relative entropy instead of divergent von Neumann entropy, demonstrating that the variation of the boundary relative entropy between a vacuum and a coherent state equals the variation of the bulk geodesic length divided by to linear order.
This paper demonstrates that 1-loop quantum corrections lift many "core" fortuitous cohomologies in and super-Yang-Mills theories while leaving lighter "hairy" states unlifted, revealing that the entropy of classical cohomologies in the Cardy limit exceeds that of strictly protected states by approximately 1.2%.
This paper demonstrates that analytical Hubble-flow parametrisations of ultra-slow-roll inflation often conceal sharp, unphysical UV features in the underlying scalar potential, which can be systematically removed via Fourier filtering to reveal that such models typically respect Wands duality and questioning the robustness of these simple parametrisations for modeling transient non-attractor phases.
This paper presents a non-perturbative lattice QCD calculation with flavors to determine the renormalization constants for the traceless components of the energy-momentum tensor, utilizing -improved Wilson actions and shifted boundary conditions to ensure the correlation functions satisfy continuum Ward identities.
This paper presents simple, explicit analytical solutions for the renormalization group equations of the strong coupling and the top quark Yukawa coupling in the asymptotic regime, which sum logarithmic corrections to all orders and reveal that while negligibly affects , higher-order contributions of significantly influence the running of .
This paper reviews and advocates for Magnetic-Field-Independent Regularization (MFIR) and the Medium Separation Scheme (MSS) as essential frameworks for studying magnetized dense quark matter, demonstrating that these methods eliminate unphysical artifacts found in traditional schemes and reveal that superconducting phases persist at zero temperature even under strong magnetic fields.
This paper analyzes QED scattering amplitudes in a chiral medium with a constant chiral chemical potential and chiral magnetic conductivity, demonstrating the emergence of resonant behaviors in various scattering processes and computing the resulting decay rates and widths of quasi-stationary fermion and photon states.
This paper investigates the configurational temperature estimator in various matrix models and random matrix ensembles, demonstrating that it satisfies the exact Schwinger–Dyson identity and serves as a sensitive diagnostic tool for Monte Carlo simulations.
This paper presents a theoretical framework using integral transforms to derive analytic formulae for extracting spectral densities from Euclidean correlators, addressing both continuum and lattice scenarios while providing rigorous bounds to control errors arising from finite temporal extents.
This paper reveals that systematic shifts in inferred neutron star equation of state parameters with varying observational precision arise from nonlinear filtering of radius measurements through previously unidentified, nearly universal inverse mappings between stellar radius and empirical EOS parameters.
