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 demonstrates that black holes with significant synchronized or resonant bosonic hair are dynamically unstable, causing their event horizons to be ejected from the center of their scalar environments in a process termed "splitting."
This paper demonstrates that while nonanalyticities associated with dynamical quantum phase transitions in dissipative free-fermion systems can persist under purely gain or purely loss processes, they are completely smeared out as soon as both channels are simultaneously active, a phenomenon accompanied by the emergence of a nested lightcone structure in the reduced Loschmidt echo dynamics.
This paper establishes a direct connection between three-dimensional gravity with chiral boundary conditions and a class of forced integrable systems, demonstrating that the boundary dynamics are governed by a forced potential modified KdV equation where the forcing term is self-consistently determined by the eigenfunctions of an associated Schrödinger operator.
This paper reinterprets the circular Unruh effect by demonstrating that the tree-level decay of uniformly rotating particles arises from the emission of negative-energy quanta due to the absence of a global vacuum state, thereby proving that such particles cannot be stable without invoking a thermal bath.
This paper utilizes finite-temperature QCD sum rules with updated quark masses and lattice-informed condensates to predict the thermal evolution of masses and decay constants for , , and mesons up to near-critical temperatures, revealing a suppression hierarchy consistent with binding energies and confirming the -- splitting observed by LHCb.
This paper establishes a connection between Hawking radiation and the double copy by demonstrating that the particle production from a massless scalar scattering off a collapsing electromagnetic background (the single copy of the Vaidya metric) can be equivalently derived through both a diagrammatic exponentiation approach and a semiclassical ray-tracing computation, yielding a thermodynamic distribution consistent with black hole physics.
This paper introduces first-order noncommutative corrections to Einstein-nonlinear electrodynamics using a Drinfel'd twist and Seiberg-Witten map, deriving perturbative solutions for static, spherically symmetric dyonic black holes that account for both intrinsic electromagnetic nonlinearity and noncommutative geometric effects.
This paper utilizes the instanton liquid model enhanced by correlated instanton-anti-instanton pairs to derive and analyze the transverse distribution of the color Lorentz force acting on quarks in pions and nucleons, demonstrating that these force form factors are intimately related to gravitational and transversity form factors and yield results for nucleons consistent with recent lattice QCD calculations.
This paper establishes the equivalence between generalised Schur partition functions of 4d $USp(2N)$ gauge theories and vector-valued modular forms by proving they satisfy specific modular linear differential equations, while also proposing extensions and conjectures linking these functions to quantum monodromy traces and 2d rational conformal field theory characters.
This paper demonstrates that applying adiabatic regularization and smoothing the transition between inflation and subsequent cosmological epochs is essential to truncate the unphysical high-frequency rise in the primary gravitational wave power spectrum, resulting in a suppressed, oscillatory behavior at small scales.
