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.

Clifford Hierarchy Stabilizer Codes: Transversal Non-Clifford Gates and Magic

This paper extends topological stabilizer codes to a broader class of Clifford hierarchy stabilizer codes based on non-Abelian Dijkgraaf-Witten gauge theories, enabling the construction of transversal non-Clifford gates that surpass the Bravyi-König bound by achieving logical operations at the (n+1)(n+1)-th level of the Clifford hierarchy in nn spatial dimensions.

Macdonald Index From Refined Kontsevich-Soibelman Operator

This paper proposes a refinement of the Kontsevich-Soibelman operator for a specific class of 4d N=2\mathcal{N}=2 superconformal field theories with source/sink BPS quivers, providing strong evidence that its trace yields the Macdonald index and conjecturing closed-form expressions for the indices of (A1,g)(A_1,\mathfrak{g}) Argyres-Douglas theories.

Poles-zeros duality in semi-holographic Mott insulators

Inspired by the poles-zeros duality in Mott insulators, this paper proposes a semi-holographic model where a fundamental fermion hybridizes with a strongly interacting sector, revealing that the resulting Green's function zeros arise from self-energy poles and can be understood through the choice of quantization schemes in the holographic framework.

The fate of Reissner--Nordström--de Sitter black holes: nonequilibrium discharge and evaporation

This paper presents a semiclassical framework combining 2D dilaton gravity and Polyakov anomaly backreaction to demonstrate that Reissner–Nordström–de Sitter black holes undergo rapid discharge via Schwinger pair production followed by monotonic mass loss, ultimately evolving toward empty de Sitter space rather than settling into classical extremal or lukewarm attractors.

Two asymptotically flat spinning black holes balanced by their self-interacting, synchronised scalar hair

This paper investigates how quartic scalar self-interactions influence asymptotically flat, balanced configurations of two spinning black holes with synchronised scalar hair, revealing that repulsive interactions drive topological changes in ergoregions and broaden analytical models but cannot increase horizon mass, whereas attractive interactions are required to achieve larger mass fractions.
