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.
The paper proposes a "mirror dual symmetry" principle for the quantum Rabi model and the Dirac equation, suggesting that enforcing a total energy of zero through paired positive and negative energy excitations could eliminate the need for the artificial Dirac sea and potentially resolve major issues in modern physics such as dark matter, dark energy, and quantum gravity renormalization.
This paper demonstrates that in JT gravity coupled to a large- bath, the capacity of entanglement serves as a sensitive probe to detect finite- replica structure within the factorized island branch that remains invisible to the von Neumann entropy at late times.
This paper employs exact WKB analysis and resurgence theory to unify the quantization of non-Hermitian inverted triple-well systems, deriving exact median-summed spectra that clarify PT-symmetry breaking, characterize exceptional points via algebraic relations between bounce and bion actions, and demonstrate the complex conjugate relationship between resonance and anti-resonance spectra.
This paper establishes a fully field-theoretic derivation of chiral edge modes in abelian Chern-Simons theory on a strip by identifying general local boundary conditions that yield opposite Kac-Moody algebras and velocity-independent edge dynamics through a holographic-like bulk-boundary matching.
This paper establishes and validates two precise quantum field theory prescriptions for deriving geodesic motion from localized single-particle states in global AdS: one based on the covariant expectation value of the stress tensor and another utilizing position operators derived from the Klein-Gordon inner product, thereby demonstrating how bulk localization and classical trajectories emerge from the distribution of CFT states over global descendants.
This paper calculates the resummed perturbative free energy of four-dimensional supersymmetric Yang-Mills theory to order in the 't Hooft coupling, demonstrating that all infrared divergences cancel, comparing different regularization schemes and Padé approximants, and showing that the theory exhibits superior convergence properties compared to QCD.
This paper utilizes a previously proposed infrared vacuum wave functional for $SU(N)$ Yang-Mills theory, which is peaked at thin center vortices and reproduces the Wilson loop area law, to calculate the spatial 't Hooft loop and demonstrate that it yields a perimeter law, thereby confirming 't Hooft's criterion for confinement.
This paper demonstrates that artificial neural networks can accurately reconstruct bulk spacetime metrics from boundary entanglement entropy and Wilson loop data, effectively resolving degeneracies in finite-density holographic models and achieving sub-0.2% accuracy without relying on closed-form derivative relations.
This paper introduces a novel, diagram-free method that combines the Heat Kernel and Background Field Method to compute gauge-invariant effective potentials, anomalous dimensions, and renormalization group equations solely from background field dynamics by consistently treating open and closed derivatives, a formalism validated through Scalar QED, Yukawa theory, and the bosonic Standard Model.
This paper numerically demonstrates the linear stability of the two-dimensional MSW stringy black hole under intrinsic metric-dilaton perturbations by showing that all quasinormal modes have negative imaginary frequencies, while revealing that these intrinsic modes exhibit oscillatory behavior and relaxation dynamics distinct from external scalar-field perturbations.
