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.
Using DESI DR2 BAO measurements, this paper constrains a model of interacting dark matter and radiation that induces bulk viscosity to resolve cosmic tensions, finding that the data disfavors such interactions prior to recombination and rules out the model as a solution to the Hubble tension.
This paper extends the study of regularization scheme dependence in supersymmetric sigma models to the five-loop order, identifying a specific renormalization scheme where the fifth-loop contribution vanishes and the fourth-loop term becomes a coordinate-independent invariant for models such as complete -duals of -deformed $SU(n)/U(n-1)$ and - or -deformed $SU(2)/U(1)$ and $SU(3)/U(2)$ models.
This paper analyzes the consistency of deforming the Heisenberg algebra within constrained Hamiltonian systems to induce Generalized Uncertainty Principle theories on the reduced Poisson algebra, specifically examining scenarios involving rotational invariance and single Hamiltonian constraints relevant to General Relativity and cosmology.
This paper provides a complete classification of finite-rank conformal Hamiltonians in one-dimensional quantum mechanics by establishing their conformal symmetry conditions, demonstrating that their correlation functions are homogeneous polynomials determined by the one-dimensional conformal Ward identities.
This study demonstrates the first observation of robust, coherent non-Abelian hadron dynamics on a noisy 156-qubit quantum processor by simulating a 60-site SU(2) lattice gauge theory using a hardware-efficient encoding, successfully capturing meson propagation and breathing modes while outperforming classical approximation methods in the weak-coupling regime.
This paper demonstrates that type II loci in the moduli space of type IIB string theory compactified on Calabi-Yau manifolds arise from integrating out a non-perturbative sector of light electric and magnetic states, which admits an effective weakly-coupled infrared description via a complex-charged BPS state and implies the existence of infrared emergent infinite distance loci in quantum gravity.
This paper develops and applies the Batalin-Fradkin-Vilkovisky (BFV) formalism to quantize off-diagonal solutions of Einstein's equations on Lorentz manifolds with nonholonomic fibrations, demonstrating that these solutions encode Hořava-Lifshitz configurations with anisotropic scaling and effective cosmological constants in the quasi-classical limit.
This paper develops a systematic effective field theory framework to calculate model-independent corrections to the quasinormal modes of Kerr black holes with arbitrary spin, revealing that near-extremality corrections exhibit an oscillatory dependence on the logarithm of a dimensionless temperature parameter, indicative of an underlying discrete-scale-invariant structure.
This paper investigates Krylov complexity in holographic six-dimensional superconformal field theories by analyzing massive geodesic probes in massive type IIA supergravity, demonstrating that while internal symmetries and quiver structures influence early-time dynamics, the late-time growth of the generalized proper momentum remains linear, consistent with operator growth in conformal theories.
This paper investigates the production of global vortex-antivortex pairs in 2+1 dimensions through numerical scattering experiments where a complex scalar field and a real scalar scatterer interact solely via a quantum mediator, revealing that vortex creation is highly sensitive to initial conditions and exhibits a chaotic parameter space with isolated production regions.
