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.

Topological spectral form factor reveals emergent non-Hermitian single-particle PT\mathcal{PT} transitions from many-body quantum chaos

This paper introduces the topological spectral form factor (TopSFF) as a non-perturbative probe that maps the dynamics of 1D many-body chaotic systems with topological defects to an emergent non-Hermitian single-particle problem, revealing a PT\mathcal{PT} symmetry breaking transition at a critical interaction strength that governs the system-size scaling behavior of the TopSFF.

Gravitational Wave Probe of Singlet-Doublet Dark Matter Induced Radiative Neutrino Mass

This paper proposes a one-loop radiative neutrino mass model featuring singlet-doublet dark matter and Z2\mathcal{Z}_2-odd scalars, demonstrating that quartic Higgs-scalar interactions can induce a first-order phase transition producing observable gravitational waves while simultaneously satisfying constraints from neutrino mass, the muon anomalous magnetic moment, and lepton flavor violation.
