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 investigates the asymptotic symmetry structure of Jackiw-Teitelboim supergravity within a BF framework, demonstrating how the dilaton supermultiplet dynamically reduces the affine symmetry to a specific subalgebra with an abelian ideal, thereby providing a consistent bulk-based framework for studying boundary dynamics beyond the Schwarzian regime.
This paper introduces magic-augmented Clifford circuits as a resource-efficient method to generate approximate unitary and state -designs with reduced circuit depth and magic gate usage, while also providing a statistical mechanics framework for their analysis and establishing no-go theorems for certain architectures.
This paper formulates a ten-dimensional holomorphic supergravity on a Calabi-Yau five-fold that reproduces heterotic moduli equations, exhibits factorized anomalies reconstructing a double-extension complex for moduli counting, and is conjectured to be an $SU(5)$-twisted version of supergravity related to the Costello-Li theory.
This semi-historical article provides a basic presentation of quantum field theory's mathematical formalism and its essential features, such as particle creation and destruction, to readers familiar with classical and non-relativistic quantum mechanics while also aiming to engage interested non-physicists.
This paper proposes a novel mechanism for generating high-frequency gravitational waves at approximately Hz through gravitational transition radiation, where particles emit gravitons as their masses change while traversing expanding bubble walls during first-order phase transitions in the early Universe.
This paper demonstrates that higher-dimensional holographic conformal field theories exhibit ETH-monotonicity, a property reinforcing the second law of thermodynamics that becomes dominant in small black hole microstates and is linked to horizon curvature, whereas its absence in two-dimensional theories aligns with the lack of curvature singularities in BTZ black holes.
This paper proposes that the GW190521 event could be a gravitational wave echo from a wormhole remnant in another universe, but concludes that Bayesian model selection strongly favors the standard binary black hole merger hypothesis over this exotic alternative.
This paper demonstrates that the threshold for primordial black hole formation in a radiation-dominated universe depends not only on the compaction function but also on the spatial curvature of the core, leading to a trichotomy of initial conditions (open, closed, or flat) that significantly influence formation probabilities, mass spectra, and the potential connection to Type-II black holes and the NanoGrav signal.
This paper develops an analytic field-theoretic approach to interacting two-body tunneling by deriving the Bethe-Salpeter equation for a Yukawa-coupled tunneling field, demonstrating a closed-form solution in the 1+1 dimensional instantaneous positive-energy regime, and confirming physical consistency through the recovery of the Lippmann-Schwinger equation.
This paper investigates nonconformally Ricci-flat gravitational instantons in four-dimensional Conformal Gravity, analyzing their conserved charges, regularity, and self-duality in both vacuum and the presence of nonlinear conformal matter fields such as scalar fields and ModMax electrodynamics.
