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 in axion monodromy inflation, oscillatory modulations of the potential continuously excite heavy moduli fields, thereby invalidating the conventional single-field approximation and generating detectable cosmological collider signals in the primordial bispectrum that bypass standard Boltzmann suppression.
This paper demonstrates that a first-order knot transition in the complex eigenvalue spectrum of a non-Hermitian Hamiltonian can emerge from a topological phase transition in an underlying Hermitian model defined by the non-Hermitian system's singular values, a process characterized by discrete jumps in eigenvalues rather than exceptional points.
This paper investigates the vacuum properties of the Proca field between parallel plates in (D+1)-dimensional Minkowski spacetime under perfect electric and magnetic conductor boundary conditions, revealing that while most vacuum expectation values converge to their massless counterparts in the zero-mass limit, the energy-momentum tensor under magnetic conductor conditions remains distinct due to the unique constraints imposed on the longitudinal polarization mode.
This paper investigates a cosmological model where a Gauss-Bonnet-coupled scalar field (dark energy) interacts with fermionic dark matter, demonstrating that both exponential and power-law potentials yield expansion histories consistent with current observational data and the standard CDM model while allowing for testable deviations in gravitational wave propagation.
This paper investigates the asymptotic symmetries of the four-dimensional Nappi-Witten plane wave spacetime, revealing a new infinite-dimensional symmetry algebra with non-trivial central extensions under specific boundary conditions that encompasses the phase space of general four-dimensional pp-waves, including the Penrose limit of Kerr black holes.
By leveraging GPU acceleration to simulate monitored noninteracting fermions on unprecedentedly large lattices, this study quantitatively characterizes entanglement dynamics, confirming the absence of a measurement-induced phase transition (MIPT) in 1D while identifying a distinct MIPT with a critical exponent of in 2D that challenges existing non-linear sigma model predictions.
This paper challenges the conventional view that black holes must contain singularities or Cauchy horizons by demonstrating that a charged, evaporating black hole can remain non-singular due to electromagnetic repulsion and Hawking radiation-induced energy condition violations, a mechanism the authors suggest may also apply to rotating astrophysical black holes.
This paper presents a causal, compositional framework for the regularized measurement of spacetime-localized observables in bosonic quantum field theory, explicitly demonstrating how time-extended measurements avoid superluminal signaling while inducing self-back-reaction and correlations within their causal future.
This paper investigates the FLPR model within a BRST-related symmetry framework, demonstrating that Gribov ambiguities in gauge-fixed actions violate the system's initial discrete symmetries and providing insights into analogous issues in QCD through variable associations.
This paper investigates the behavior of straight and wiggly cosmic strings in linearized Horndeski theory, demonstrating that a massive scalar field induces a screening effect that causes the solutions to approach those of general relativity.
