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.

These lecture notes from Les Houches offer a concise overview of the conceptual, computational, and mathematical foundations of tensor networks, presenting them as a powerful framework for understanding and simulating strongly correlated quantum matter by leveraging entanglement structures to overcome the many-body exponential wall.
This paper numerically constructs and analyzes a family of critical spacetime crystals in arbitrary continuous dimensions , determining their echoing periods and Choptuik exponents as continuous functions of and supporting these findings with analytical expansions that suggest both quantities vanish as approaches 3.
This paper demonstrates that the severe partial-wave unitarity violations found in non-relativistic radiative bound-state formation calculations are resolved by properly resumming the inelastic contributions to the incoming state's self-energy.
This paper establishes a comprehensive set of matrix-based degeneracy conditions and consistency constraints for multi-field higher-order scalar-tensor theories that successfully eliminate unwanted Ostrogradsky modes, ensuring the propagation of only the two tensor and scalar degrees of freedom.
This study employs the dynamical hadronization technique within the functional renormalization group approach to two-flavor QCD to derive low-energy constants for the pion, -meson, and scalar diquark from first principles, thereby providing microscopic constraints for models of dense quark matter and color superconductivity.
This paper demonstrates that tree-level gluon correlators in can be systematically expanded into a sum over energy poles with residues given by flat-space scattering amplitudes, utilizing a recursive AdS analogue of Berends-Giele currents to provide an elegant, all-multiplicity formula for computing full correlators without relying on individual Feynman diagrams.
This paper extends the criteria for exciting one Gaussian state from another in generalized free field theories to include states with nonzero vacuum expectation values, proving that excitability requires both specific conditions on connected two-point functions and a bounded difference in VEVs, and demonstrating that in anti-de Sitter spacetime, a VEV shift is excitable if and only if its boundary extrapolation is excitable in the dual conformal field theory.
This review synthesizes the hydrodynamic, relativistic, and quantum mechanisms governing Primordial Black Hole formation and evolution, challenging standard Hawking evaporation models by proposing Planck-scale relics and highlighting the potential for next-generation gravitational wave observatories to provide definitive evidence for their existence as dark matter candidates.
This paper provides a detailed review of the geometric foundations of the Batalin-Vilkovisky formalism, specifically focusing on forms and half-densities, and explains their integration into the quantum odd symplectic category via the odd quantization functor.
This paper demonstrates that requiring a causal, stable, and thermodynamically consistent extension of neutron-star equations of state to higher densities strongly disfavors purely nucleonic models and supports the presence of additional degrees of freedom in massive stable neutron stars.
