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 rigorous, real-valued operator-algebraic definition for timelike entanglement entropy in quantum field theory, supported by the timelike tube theorem and corroborated by path integral and holographic perspectives.
This paper investigates how a harmonically trapped detector responds to classical versus non-classical gravitational fields, demonstrating that while coherent states can be mimicked by stationary classical fields, squeezed states induce unique non-linear time dependencies in transition probabilities due to correlation functions that cannot be replicated classically.
This paper extends multivariable knot polynomials derived from braided Hopf algebras to link invariants, thereby confirming conjectures that identify specific instances of these new invariants with known link polynomials.
This paper establishes a holographic correspondence between bulk gravitational radiation in asymptotically locally anti-de Sitter spacetimes and dissipative fluid dynamics in the dual boundary theory, extending this framework to the flat limit to reveal how bulk radiation sources Carrollian viscous stress and heat currents in flat-space holography.
This paper demonstrates that for dynamical black holes in theories, the Hollands-Wald-Zhang entropy equals the Wald entropy on the generalized apparent horizon, and establishes that only the apparent horizon prescription correctly reproduces this entropy via the replica method while satisfying the physical process first law and a reformulated generalized second law.
This paper proposes a first-principles framework using gradient flow and renormalization group transformations to analytically derive confinement in QCD, demonstrating that a scale-invariant gluon condensate drives the running coupling to an infrared fixed point consistent with infrared slavery.
This paper resolves controversies regarding the particle spectrum of pure gravity by demonstrating through a full Hamiltonian analysis that while the theory propagates three degrees of freedom globally, its linearized spectrum around Minkowski and other spacetimes is empty due to a constraint degeneracy that renders these backgrounds surfaces of strong coupling, although the universe can still evolve through such singularities.
This paper presents a comprehensive study of the Muonic Portal to Vector Dark Matter model, demonstrating its ability to simultaneously explain dark matter relic abundance and muon anomalies through a novel velocity-suppression mechanism while establishing stringent collider bounds on vector-like muon masses and predicting distinctive multi-lepton signatures for future searches.
This paper constructs the graviton propagator in de Sitter space within a generalized one-parameter non-covariant gauge family, providing a simplified form to facilitate future checks of gauge dependence in one-loop computations and proposed observables.
This paper revisits Einstein-Kalb-Ramond gravity to derive two distinct classes of exact static black hole solutions with general topological horizons in diverse dimensions, analyzes their thermodynamic properties using the Wald formalism to establish the first law and clarify the role of Noether mass, and discusses the observational implications of these findings.
