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 compares effective quantum gravity and trace anomaly approaches to calculating quantum corrections to the Newtonian potential in the Boulware vacuum, finding that they yield different results unless the asymptotic behavior of the energy-momentum tensor is modified to reconcile the two methods.
This paper proposes a Physics-Informed Neural Network framework that formulates lattice fermions as an optimization problem, successfully reconstructing the overlap fermion operator and autonomously discovering both standard and generalized Ginsparg-Wilson relations without relying on predefined approximations.
This paper demonstrates that spontaneous symmetry breaking in non-abelian gauge theories alters field cohomology to create matter-like properties, which naturally resolves the Gribov ambiguity on-shell when constructing a renormalizable unitary gauge via Morse's functional extremization.
This paper constructs non-invertible duality defects in (2+1)d quantum field theories by performing half-spacetime gauging of 2-group symmetries derived from parent theories with discrete Abelian symmetries and mixed anomalies, explicitly deriving the resulting fusion rules and illustrating the framework with specific gauge theory examples.
This contribution presents an algebraic tensor ring decomposition framework that systematically maps nonlinear Yang-Mills equations into tractable differential-algebraic systems and, through the analysis of differential ideal bifurcations and quotient rings, enables the extraction of three distinct classes of exact solutions—including relativistic color waves, dynamic dyonic flux tubes, and $SU(3)$ configurations.
These lecture notes bridge classical statistical physics and neural networks by introducing key concepts like phase transitions and the renormalization group to explain models such as Ising spins, Hopfield networks, and Boltzmann machines, ultimately connecting these foundations to modern deep learning and large language models.
This paper demonstrates that non-planar corrections in the symmetric orbifold lift degeneracies in the spectrum of quarter BPS states and induce signatures of quantum chaos, suggesting that integrability is restricted to the planar (large ) limit.
This paper reinterprets the Hagedorn temperature in string theory as a nonequilibrium dynamical bottleneck using Steepest-Entropy-Ascent Quantum Thermodynamics, demonstrating how the exponential density of states and its algebraic prefactor govern the slowing-down of effective intensive variables and the breakdown of thermodynamic descriptions.
This paper presents an explicit formula for the -site chain graph contribution to the cosmological wavefunction in de Sitter space for conformally coupled theory by proving that these coefficients can be expressed using Rudenko's quadrangular polylogarithms, which form a complete basis for functions compatible with the cluster algebra.
This paper introduces a solution-dependent superpotential-like function to resolve the variational problem and achieve holographic renormalization for four-dimensional Einstein gravity with mixed boundary conditions, demonstrating how the boundary deformation fixes the near-boundary expansion of to render the on-shell action finite without additional scalar boundary terms.
