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 computes the renormalized expectation values of the scalar condensate, charge current, and stress-energy tensor for a massive charged quantum scalar field in various quantum states on a Reissner-Nordström black hole background, utilizing efficient numerical methods to explore a wide parameter space including near-extremal charges and masses near the superradiant limit.
This paper develops a stochastic formulation of the Schwinger effect in de Sitter and generic FLRW spacetimes using the Schwinger-Keldysh formalism to describe particle production by non-stationary gauge backgrounds, establishing a framework applicable to early-Universe phenomena like inflation and preheating without relying on asymptotic out states.
This paper demonstrates that while Lorentzian Kähler fermions on Minkowski spacetime are inherently non-unitary when interpreted as antisymmetric tensor fields, unitarity can be restored via a modified inner product involving an operator that ensures positive norms but breaks Lorentz covariance, ultimately rendering the theory equivalent to four Dirac fermions in flat space.
This paper proposes a novel framework interpreting holographic bit threads as trajectories of quantum information flow within categorical quantum mechanics, demonstrating that their nonuniqueness naturally arises from distinct protocols achieving the same entanglement distillation and revealing finer entanglement structures beyond standard entropy measures via ZX string diagrams.
This paper proposes a realist, anti-wavefunction interpretation of quantum field theory grounded in an expanded ontology inspired by the renormalization group, using a non-interacting scalar field toy model to demonstrate how Planck's constant emerges as a temperature-dependent, observer-relative quantity flowing toward a fixed point.
This paper proposes a novel method for computing Schwarzschild black hole quasinormal modes by mapping the problem to bound states via coordinate transformation and analytic continuation, identifying the method's accuracy limitations for high overtones through singularity analysis in the complex plane, and mitigating these issues by introducing a homotopy deformation to the potential.
This paper revisits the Moore-Read construction of Laughlin states on compact Riemann surfaces by deriving their conformal blocks from Chern-Simons theory, computing explicit monodromies for quasi-hole transport and flux insertion, and demonstrating how these results recover classical Hall conductance values while connecting to modern algebro-geometric approaches.
Motivated by the recent LHC excess, this paper investigates whether a top-philic Type-III Two-Higgs-Doublet Model can simultaneously explain the anomaly and generate the observed baryon asymmetry of the Universe through electroweak baryogenesis, finding that while the model supports a strong first-order phase transition, only the explicit CP violation scenario remains viable within the current one-loop treatment compared to the transitional CP violation scenario.
This paper employs a non-perturbative open quantum system framework to demonstrate that both pure gravitational and null electromagnetic impulsive plane waves suppress the excitation transitions of an Unruh-DeWitt detector modeled as a harmonic oscillator interacting with a massless scalar field.
This paper constructs nonunitary 2d gauged linear sigma models with supergauge groups to establish super-Grassmannian generalizations of key mathematical correspondences, including Calabi-Yau/Landau-Ginzburg dualities, birational equivalences via flop transitions, and homological projective dualities via conifold transitions.
