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 explores traversable wormhole solutions in gravity supported by Rényi, Moradpour, and Bekenstein–Hawking holographic dark energy models, demonstrating that while the resulting shape functions satisfy geometric traversability criteria, the null energy condition is inevitably violated, necessitating exotic matter or an effective exotic sector.
This paper employs the Schwinger-Keldysh formalism to derive and renormalize the one-loop effective action for a scalar field in de Sitter spacetime, demonstrating that nonlocal quantum corrections introduce memory and noise terms that suppress the field's infrared variance compared to tree-level predictions.
This paper establishes a flow loop formula for the skein-valued partition function of Lagrangian knot complements using holomorphic curve counting, demonstrating that for torus knots the partition function localizes on specific holomorphic annuli and satisfies a -difference equation that quantizes the knot's augmentation curve, thereby providing a new geometric coordinate chart for the associated -module.
This paper presents a local subtraction scheme that enables the fully numerical integration of real-virtual NNLO QCD corrections for electroweak production by systematically modifying Feynman integrands to achieve local infrared finiteness and gauge symmetry cancellations in momentum space.
This paper employs a nonperturbative Hamiltonian framework using Daubechies wavelets in momentum space to analyze dimensional theory, successfully demonstrating the emergence of a strong-coupling phase transition in the sector.
Motivated by Maldacena's observer-centric formulation, this paper develops a relational state-counting framework in Euclidean de Sitter space where an observer modeled as a massive worldline with an SU(3) clock cancels negative gravitational modes and, via a Hamiltonian constraint, yields a real and positive microcanonical density that links the cosmological constant and fundamental constants to SU(3) confinement.
This paper proposes a scalable superconducting-circuit architecture that utilizes the intrinsic infinite-dimensional Hilbert space of rotor variables to realize compact U(1) lattice gauge theory with exact Gauss's law and emergent gauge dynamics, offering a continuous-variable platform for analog quantum simulation without the need for Hilbert-space truncation or auxiliary stabilizers.
This paper introduces a new causal spinfoam vertex for 4d Lorentzian quantum gravity that utilizes Toller matrices to encode causal data, demonstrating that in the large-spin limit, this formulation selects only Lorentzian Regge geometries with compatible causal structures, yielding a single Regge action exponential and establishing a new form of causal rigidity.
This paper demonstrates that the Kontsevich-Segal-Witten criterion for the allowability of complex metrics in the gravitational path integral for AdS black holes with two angular momenta is equivalent to the convergence conditions of the microscopic supersymmetric index, thereby extending previous equivalences found in simpler spacetime examples.
This paper utilizes the worldline formalism to present a unified one-loop calculation of photon-graviton mixing in an electromagnetic field, identifying a previously overlooked tadpole diagram that contributes to the amplitude but does not affect magnetic dichroism, while also extending the analysis to include scalar loops and electric field components.
