hep-th papers | Gist.Science

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.

Memory Effects and Entanglement Dynamics of Finite time Acceleration

This paper investigates the memory effects and entanglement dynamics of Unruh-DeWitt detectors undergoing finite-duration uniform acceleration in Minkowski spacetime, revealing that while CP divisibility and Fisher information exhibit memory-dependent behaviors, total correlations and entanglement harvested return smoothly to their initial values after the acceleration phase without measurable impact on negativity or mutual information.

Unique gravitational wave signatures of GLPV scalar-tensor theories

This paper identifies a unique scalar-scalar-tensor interaction in GLPV scalar-tensor theories that generates third-derivative source terms, leading to a significantly enhanced production of induced gravitational waves with a characteristic $f^5$ spectral density that distinguishes them from Horndeski-related models.

Magnetization by Rotation: Spin and Chiral Condensates in the NJL Model

This paper investigates how spin condensates, arising from rigid rotation in the Nambu-Jona-Lasinio model, can counteract the rotational suppression of chiral condensates and potentially shift the chiral phase transition from second to first order.

Black Hole Entropy and Complexity Growth in Horndeski Gravity within the AdS/BCFT Framework

This paper extends the AdS/BCFT correspondence to Horndeski gravity, demonstrating that the linear growth of holographic complexity and the switchback effect persist for rotating and charged black holes when the theory's effective causal structure aligns with the background metric, thereby supporting the "complexity=action" conjecture in scalar-tensor theories.

Three-point functions in critical loop models

This paper conjectures an exact formula for three-point functions of $\ell$ -leg and diagonal fields in two-dimensional critical non-intersecting loop models, which is supported by agreement with Conformal Loop Ensemble results and numerical transfer matrix computations on cylindrical lattices, with minor discrepancies attributed to degenerate ground states in the Jones-Temperley-Lieb algebra.

Lattice-reflection symmetry in tensor-network renormalization group with entanglement filtering in two and three dimensions

This paper proposes a method to incorporate lattice-reflection symmetry into the tensor-network renormalization group (TNRG) with entanglement filtering for both two and three dimensions by defining the symmetry in tensor-network language and introducing a transposition trick to preserve it during key operations, thereby enabling the separate extraction of scaling dimensions in specific symmetry sectors.

O(16) $\times$ O(16) heterotic theory on $AdS_3\times S^3\times T^4$

This paper demonstrates that non-supersymmetric $AdS_3 \times S^3$ vacua in the $O(16) \times O(16)$ heterotic theory, while stable against scalar and tensor fluctuations above the Breitenlohner-Freedman bound, cannot be uplifted to de Sitter space by the one-loop scalar potential regardless of flux values.

Surprising one-loop finiteness of 6D half-maximal supergravities

This paper demonstrates that six-dimensional half-maximal supergravities coupled to specific numbers of tensor and vector multiplets (corresponding to type II string theory compactifications on K3) exhibit surprising one-loop ultraviolet finiteness for four-matter and two-matter two-graviton amplitudes, despite the existence of symmetry-preserving counterterms.

Constraints on Axion-photon coupling from the Global 21-cm Signal

This paper analyzes constraints on axion-photon coupling from global 21-cm signal observations and identifies viable parameter regions where parametric resonance can simultaneously satisfy observational limits and support the formation of primordial magnetic fields and direct collapse black holes.

Holographic Black Hole Formation and Scrambling in Time-Ordered Correlators

This paper proposes a holographic mechanism where the collision of two shock waves in 3D AdS spacetime, dual to boosted precursor operators in a CFT, leads to black hole formation after two scrambling times, a process diagnosed by the exponential growth of operator dimensions in time-ordered correlators that reveals scrambling characteristics typically associated with out-of-time-order functions.
