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.

This paper constructs a nonlocal extension of the Rarita-Schwinger theory for spin-3/2 fermions using scalar and Dirac-operator form factors, demonstrating that the theory preserves physical constraints, avoids unphysical spin-1/2 dynamics, and remains ghost-free at the free level while introducing modified dispersion relations.
This paper demonstrates that a movable, quantum-fluctuating conducting plate separating two scalar field cavities induces effective interactions that generate entanglement between field modes in the sub-cavities, a phenomenon absent when the wall is fixed.
This paper presents the comprehensive theory of graphical functions in even dimensions greater than or equal to four, offering detailed reviews of their properties and full proofs to facilitate the calculation of Feynman periods and renormalization constants in high-loop quantum field theories.
Using the AdS/CFT correspondence to study superfluid phase transitions in a disk geometry, this paper demonstrates that while vortex density follows Kibble-Zurek scaling for slow quenches and a distinct universal scaling for fast quenches, the underlying vortex statistics are best described by a Poisson binomial distribution across both regimes, revealing universal defect distribution laws that extend beyond traditional KZM predictions.
This paper demonstrates that quadratic modified teleparallel gravity provides a self-consistent framework for nonsingular bouncing cosmology, where dynamical system analysis confirms a smooth transition from contraction to expansion without singularities, featuring a phantom-like phase and a stable late-time attractor.
This paper demonstrates that a non-Abelian gauge model with a complex isovector scalar field and a sixth-order potential supports a nontopological soliton featuring a monopole-like core, a Q-ball-like shell, and a long-range dipole chromomagnetic field whose moment scales with the soliton's linear size.
This paper demonstrates that wavepackets propagating across topological interfaces and duality defects in quantum spin systems experience perfect transmission while converting into nonlocal string-like excitations, offering a systematic lattice construction method that provides an operational meaning to topological interfaces and resolves the monopole paradox.
This paper develops a canonical Post-Newtonian Hamiltonian framework for radiating charges by integrating the Landau-Lifshitz reduced radiation reaction force with the Darwin Hamiltonian to derive inspiral laws for charged binaries, extending the analysis to Einstein-Maxwell theory to establish gauge-invariant energy-frequency relations and identify the crossover scale between electromagnetic dipole and gravitational quadrupole flux dominance.
This paper generalizes the concept of family anomalies to broken generalized and categorical symmetries, utilizing anomaly inflow and SymTFTs to constrain the renormalization group flows and infrared phases of families of quantum field theories, with specific applications to 4d QCD-like theories deformed by multi-fermion interactions.
Using a large- renormalization group approach, this paper demonstrates that three-dimensional generalized Weyl semimetals with monopole charge exhibit an anisotropic marginal non-Fermi liquid phase driven by amplified Coulomb interactions, characterized by intrinsically anisotropic screening and power-law quasiparticle suppression, in contrast to the isotropic behavior found in systems with .
