4348 papers

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.

Holography from number theory: Emergent holographic AdS2_2 space-time from exact BPS black hole microstate counting

This paper demonstrates that the exact number-theoretic counting of 4D BPS black hole microstates via Rademacher expansions can be mapped to a Segal-Bargmann heat kernel calculation in a conformal quantum mechanics model, thereby revealing the holographic emergence of an AdS2_2 bulk geometry and deriving the Bekenstein-Hawking entropy along with its corrections from entanglement entropy.

The BPHZL renormalization of a planar quantum electrodynamics up to 2-loops and beyond

This paper demonstrates the ultraviolet and infrared finiteness of a parity-even, massless U(1)×U(1)U(1)\times U(1) quantum electrodynamics in three dimensions up to two loops and beyond by employing the BPHZL renormalization method combined with the Lowenstein-Zimmermann subtraction scheme to address infrared divergences arising from ultraviolet subtractions.

Spontaneous baryogenesis with large misalignment

This paper investigates particle production by a pseudo-Nambu-Goldstone boson in the spontaneous baryogenesis scenario with large misalignment angles, demonstrating through numerical studies in both Minkowski and FLRW spacetimes that the baryon asymmetry's cubic dependence on initial phases breaks down for large oscillations, leading to saturation near π\pi and a strong sensitivity to the field's damping rate.

Quiver superconformal index and giant gravitons: asymptotics and expansions

This paper investigates the large-NN asymptotics of the superconformal index for d=4d=4, N=1\mathcal{N}=1 toric quiver gauge theories using graph-theoretic and algebraic techniques to derive cycle expansions, identify Hardy-Ramanujan-type or polynomial growth behaviors for specific geometries, and generalize giant graviton expansions to multi-matrix models.

Van der Waals interaction at short and long distances: a pedagogical path from stationary to time-dependent perturbation theory

This paper presents a unified pedagogical framework that reformulates stationary perturbation theory using time-ordered correlation functions to simplify the derivation of van der Waals interactions across both short-distance (London) and long-distance (Casimir-Polder) regimes, effectively bridging standard quantum mechanics with field-theoretic treatments.
