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.

This paper demonstrates that by applying an action-based procedure to remove spurious higher-derivative degrees of freedom from general relativity supplemented with cubic Riemann terms, the resulting effective theory of gravity can be reformulated as a minimally modified gravity model that propagates only the massless spin-2 graviton while exhibiting a preferred frame at short distances.
This paper demonstrates that various quantum information measures, including magic, trace distance, and fidelity distance, offer distinct and complementary sensitivities to new physics in the top quark sector within the Standard Model Effective Field Theory, highlighting the importance of employing multiple such metrics to effectively probe beyond-Standard-Model phenomena.
This paper establishes a unified resource theory for non-stabilizerness in hybrid boson-fermion systems by introducing a Grassmann phase-space framework based on the norm of a hybrid Wigner function, which is then applied to quantify magic growth in models like the Holstein polaron and fermionic Jaynes-Cummings system as well as to derive the non-stabilizer power of hybrid quantum gates.
This paper establishes a formal correspondence between topological quantum neural networks (TQNNs), which implement universal quantum computation and error correction via Reshetikhin-Turaev and Turaev-Viro models, and amplituhedra, thereby demonstrating that amplituhedra serve as geometric representations of generic quantum processes rooted in underlying topological structures.
This paper proposes that in the holographic dual of 4d super Yang-Mills theory, topological operators for continuous non-Abelian symmetries are realized as bound states of D5-branes and Kaluza-Klein monopoles hanging from the boundary, which satisfy Gauss' law constraints and measure the representations of Wilson line endpoints.
This paper employs the semi-classical BPS Skyrme model to accurately compute electromagnetic and neutral current form factors for heavy nuclei using only a single global radial parameter, offering a robust alternative to phenomenological approaches that is crucial for reducing systematic uncertainties in precision neutrino experiments.
This paper develops a comprehensive path-integral framework for thermal gauge theories in rotating plasmas with arbitrary temperature, chemical potentials, and angular momentum, deriving generalized KMS conditions and demonstrating that while thermal propagators are modified by these parameters, interaction vertices remain unaltered.
This paper extends the Verlinde-van der Heijden quantum information retrieval protocol to charged black holes by incorporating type III von Neumann algebras, thereby deriving a thermodynamic interpretation of charge evaporation and suggesting constraints on charge quantization through the index-statistics theorem.
This paper investigates holographic charge measurement for continuous internal symmetries by characterizing charged boundary operators via bulk Wilson lines and measurement via U-shaped defects, deriving universal low-energy features, and providing explicit top-down realizations in Type IIB string theory and M-theory that elucidate the underlying brane dynamics, topological nature, and fusion rules of these configurations.
This paper proposes a method for constructing complex bulk metrics from families of complex extremal surfaces associated with timelike entanglement, utilizing the Kontsevich–Segal–Witten criterion to uniquely determine admissible integration contours and organize complex saddles in real-time holography.
