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.
This paper employs Morse-Bott theory to derive topological bounds on the homology and topology changes of generic compactification manifolds within smooth cobordisms to nothing, thereby extending the analysis of Bubbles of Nothing and related spacetime-ending configurations beyond simple or singular cases.
This paper introduces the projected process ensemble as a unified framework for diagnosing quantum chaos in many-body systems, demonstrating that its higher moments reveal characteristic entanglement structures that more sharply distinguish chaotic from integrable dynamics than previously studied chaos quantifiers.
This paper demonstrates that excitations in spin-1 Bose-Einstein condensates can be mapped to emergent relativistic quantum field theories, including massive Proca fields, on curved acoustic spacetimes with bi- or tri-metric structures, thereby enabling the quantum simulation of cosmological particle production and spin-nematic squeezing through controlled magnetic field variations.
This paper investigates the viability of using neural network architectures with finite neurons to simulate local quantum field theories, finding that while they can reproduce results in the infinite limit, their perturbative expansions for finite suffer from weak convergence due to ultraviolet sensitivity, prompting the proposal of architectural modifications to improve accuracy.
This paper resolves the apparent tension between locality and unitarity in quantum field theories with non-invertible categorical symmetries by demonstrating that locality enforces specific regularities on symmetry actions, enabling the definition of an observable that quantifies non-locality and encodes fusion algebra data.
This paper demonstrates that while the standard and constraint definitions of a scalar field effective potential are equivalent in Minkowski spacetime, they diverge in de Sitter spacetime, with the constraint potential uniquely avoiding infrared convergence issues and serving as the correct formulation for stochastic Starobinsky-Yokoyama theory.
This paper introduces a formalism for constructing conformally invariant defects within Neural Network Field Theories (NN-FTs), demonstrating its application in two toy scalar field models and deriving an NN-based interpretation of a defect operator product expansion in two-point correlation functions.
This paper extends the deconfined quantum criticality paradigm to systems with internal supersymmetry by proposing a supersymmetric deconfined quantum critical point (sDQCP) between an $OSp(1|2)$-breaking phase and a lattice rotation-breaking phase, which is described via a non-linear sigma model on a supersphere and a gauge theory, and shown to continuously connect to the conventional DQCP when supersymmetry is explicitly broken.
This paper investigates quantum criticality in a holographic p-wave superconductor-insulator transition, demonstrating that while holographic entanglement entropy becomes insensitive to the transition at large scales, the entanglement wedge cross-section serves as a robust mixed-state entanglement probe by exhibiting pronounced critical scaling driven by bulk deformations.
This paper proposes a framework where Yukawa hierarchies emerge from powers of anarchic spurions in higher $SU(2)$ and $SU(3)$ flavor representations via progressive rank lifting, offering testable predictions for flavor-changing neutral currents and stochastic gravitational-wave backgrounds.
