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 constructs a quantum Schwinger-Keldysh effective field theory for diffusive hydrodynamics that enforces fluctuation-dissipation relations via KMS symmetry to reveal intrinsically non-Gaussian noise, ultimately deriving one-loop quantum corrections that generalize hydrodynamic long-time tails to arbitrarily high orders in .
This paper proposes a generalized hyper-cluster state model generated by Z gates that preserves symmetry to produce -fold degenerate edge states, enabling non-Clifford universal measurement-based quantum computation through the implementation of Z gates.
This paper presents a holographic model of black hole evaporation in asymptotically flat spacetimes using Brill-Lindquist wormholes and an extended HRT formula, demonstrating that the resulting entanglement entropy follows the Page curve while the restricted complexity of decoding Hawking radiation aligns with the time-dependent predictions of the Python's Lunch conjecture.
This paper demonstrates that codimension-two defects in Fermi liquids induce a marginally relevant renormalization group flow driven by spatial anisotropy-induced particle-hole asymmetry and a non-derivative coupling to localized dislon modes, distinguishing the mechanism from the Kondo problem and establishing a flow timescale proportional to the defect's length.
This paper establishes that while measuring a subsystem of a general quantum k-design typically degrades its randomness to at most a k/2-design, chaotic dynamics can reverse this loss, enabling the projected ensemble to achieve exact Haar-randomness even when the global state possesses only limited design properties.
This paper presents the first construction of three-family supersymmetric Pati-Salam models with extra gauge symmetries from intersecting non-rigid D6-branes, demonstrating how adding a -stack of branes reduces filler branes and exotic particles while generating useful vector-like states and new model classes.
This paper demonstrates that in orbifold GUTs, the axion-photon coupling-to-mass ratio () for all axions, including those localized on boundaries, is bounded by or equal to the QCD axion value due to topological constraints and unsuppressed boundary instantons.
This paper develops direct methods to compute tree- and loop-level "Magnus amplitudes" in relativistic quantum field theory, revealing that they are determined by forward limits of tree-level amplitudes and Murua coefficients, thereby providing a systematic and efficient framework for calculating classical observables like the radial action while bypassing traditional scattering amplitudes and hyper-classical terms.
This paper proposes a systematic calculational scheme based on pseudodifferential operator calculus to derive the Schwinger--DeWitt expansion for heat kernels of nonminimal operators in causal theories, utilizing a linear map from minimal operators and a specialized subtraction procedure to ensure finiteness, as demonstrated through examples like the Proca model.
This paper argues that within the Dark Dimension Scenario, standard primordial black hole production mechanisms inevitably result in five-dimensional black holes, some of which could have lifetimes comparable to the universe's age and potentially explain recent high-energy neutrino detections.
