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 demonstrates that flavor-current correlators in strongly-coupled dense holographic matter agree with non-Abelian hydrodynamic predictions in an extended hydrodynamic regime where temperature is much lower than frequency and momentum, and proposes a holographic product formula to capture both hydrodynamic and AdS pole effects.
This paper calculates time-dependent thermal one-point functions of massive operators in expanding matter-dominated universes by applying the Grinberg-Maldacena geodesic formula within a Randall-Sundrum II braneworld model containing a -brane gas, deriving results from the brane's evolving radial position determined by the Israel junction conditions.
Using holography, this paper presents the first fully backreacted computation of the cutoff-independent defect contribution to the entanglement entropy for four-dimensional superconformal RG interfaces, quantifying its dependence on supersymmetric mass deformations and relating it to the renormalized on-shell action and stress-tensor one-point function.
This paper demonstrates that binary black hole mergers with strong magnetic fields and high remnant spins can accelerate charged particles to ultra-high energies (-- eV) via the Bañados--Silk--West mechanism, identifying these events as promising sources of ultra-high-energy cosmic rays.
This paper develops a systematic analytic method based on temperature-graded Frobenius expansions to demonstrate that high-order pole-skipping in near-extremal holographic black holes is governed by near-horizon physics, where pole-skipping momenta become independent of the order and collapse onto a discrete set determined by IR conformal dimensions and thermodynamic quantities.
This paper reformulates stochastic quantization as a finite-time stochastic optimal control problem where a neural network learns a Doob-transform force to steer a reference process toward a target equilibrium distribution, thereby eliminating model bias and enabling the recovery of multimodal distributions and critical observables more efficiently than traditional equilibration methods.
This paper establishes a universal, finite-size-correction-free scaling function for the OPE coefficients of two maximal giant gravitons and a spinning operator in planar super-Yang-Mills theory, providing a systematic method to compute it at arbitrary coupling that matches known weak-coupling results and offers new strong-coupling predictions.
This paper reveals that discrete series scalars in two-dimensional de Sitter space possess a global conformal symmetry which acts non-locally on the scalar field but locally on an equivalent conformal Killing tensor description, thereby yielding a traceless stress tensor that generates these transformations.
This paper demonstrates that non-Hermitian critical chains near exceptional points exhibit a unique entanglement entropy scaling with an additional term, which arises from the de Sitter geometry of the renormalization flow and signifies that the system's entanglement remains sensitive to small energy gaps even at sub-finite scales, unlike their Hermitian counterparts.
This paper proposes that applying the quantum speed limit to string field theory via Fisher information establishes a minimum evolution time that necessitates non-local interactions, thereby potentially resolving divergences in effective quantum field theories.
