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 analytically and numerically investigates the large- free energy of the critical vector model on with angular velocity, revealing that while the leading high-temperature pole matches the free theory, sub-leading terms exhibit non-analytic behavior that distinguishes the critical fixed point from the free limit.
This paper introduces a family of coarse-grained models for canonical loop quantum gravity, constructed via a systematic spin network coarse-graining procedure and effective Hamiltonians, to establish a renormalization framework for studying continuum limits and deriving phenomenological models.
This paper extends the separate-universe approach to multifield inflation using a Hamiltonian phase-space formalism, demonstrating that the approximation accurately describes cosmological perturbations on super-Hubble scales and validating the uniform-expansion gauge for stochastic inflation applications relevant to primordial black hole production.
Using exact diagonalization of Dirac fermions on a sphere to leverage full symmetry and circumvent the parity anomaly, this study demonstrates that the interaction-driven multicritical point of the two-dimensional Chern insulator transition belongs to the Gross-Neveu-Yukawa universality class, with extracted operator scaling dimensions showing strong agreement with conformal bootstrap predictions.
This paper proposes a renormalization group-based extension of the CDM model, where the cosmological constant and Newton's constant vary with energy scale due to massive quantum fields, successfully alleviating the tension while remaining consistent with CMB, BAO, and supernova data through a best-fit parameter .
This paper establishes a unified theoretical framework for topological charge-$2ne$ superconductors by deriving them from charge- ingredients and quantum Hall states, characterizing their bulk and edge properties through field theories that predict fermionic non-abelian topological orders.
This paper presents a comprehensive reanalysis of DESI DR1 data combined with other cosmological probes, achieving percent-level constraints on key parameters and providing robust evidence favoring the normal neutrino mass hierarchy while setting the tightest bounds to date on the sum of neutrino masses and dynamical dark energy.
This paper develops a real-time Schwinger-Keldysh formulation of Krylov dynamics that treats Krylov complexity as an in-in observable, revealing an emergent phase-space description where semiclassical chaos and integrability-chaos crossovers are characterized by the behavior of Lanczos coefficients and their fluctuations.
This paper investigates giant graviton configurations in AdSSE backgrounds by characterizing their geometry through transverse Kähler potentials and conical deficits, ultimately quantizing their fluctuations to compute a protected superconformal index that reproduces the finite- results of the dual quiver gauge theories.
This paper establishes a framework for exactly reconstructing Krylov complexity for polynomially prepared initial states from a single reference cyclic system using Christoffel transforms, thereby deriving rigorous bounds on physical displacement and demonstrating universal asymptotic convergence across diverse quantum models without requiring new Lanczos recursions.
