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 investigates the universality of the entanglement viscosity to entropy density ratio for spin-3/2 fields within the Rarita-Schwinger-Adler theory, revealing that while both quantities can be negative (yielding a KSS-bound-saturating ratio), a Zubarev density operator approach confirms a positive entropy, thereby clarifying the origin of the negativity and highlighting the theory's conformal field theory features.
This paper establishes a perturbative framework for the Lorentzian Wetterich Renormalization Group flow within perturbative Algebraic Quantum Field Theory on curved spacetimes, deriving beta functions for interacting scalar and Dirac fields, exploring connections to stochastic dynamics, and proving the local well-posedness of the resulting flow equations using the Nash-Moser theorem.
This paper develops a bottom-up open effective field theory for non-Abelian gauge theories within the Schwinger-Keldysh formalism by explicitly retaining slow environmental color variables to construct a local, gauge-covariant Markov embedding that naturally recovers hard thermal loop responses and provides a systematic framework for studying color transport, memory effects, and fluctuation-dissipation in non-Abelian plasmas.
This paper investigates slow-roll inflation within a broad class of scalar-tensor Gauss-Bonnet models by deriving theoretical predictions for spectral observables and their higher-order runnings, establishing consistency equations, and constraining model parameters against the latest Planck observational data.
This paper investigates the out-of-equilibrium evolution of a superfluid in expanding backgrounds relevant to heavy-ion collisions and cosmology, identifying a novel "attractor time" that characterizes the transition to hydrodynamic attractors and revealing a unique nonlinear regime of constant anisotropy in Gubser flow alongside late-time condensate-dominated behavior in FLRW spacetime.
This paper constructs a class of regular black hole geometries with finite curvature invariants using various analytic profiles and demonstrates that their dynamical stability under axial gravitational perturbations is critically determined by the shape of the effective potential, particularly the peak-to-valley ratio.
This paper proposes a scale-invariant gravity model with a matter-dependent potential that unifies inflation, early dark energy, and late dark energy, offering a mechanism to alleviate the Hubble tension by modifying the sound horizon while remaining consistent with CMB, BAO, and local observations.
This paper establishes the universality of the chiral soliton lattice (ChSL) as a robust low-energy feature of QCD coupled to electromagnetism, demonstrating its stability against higher-order corrections and deriving the exact analytical spectrum of fermionic excitations to characterize its interaction with quark matter.
This paper proposes a new time-dependent non-equilibrium representation of the Schrödinger algebra to predict scaling functions for single-time and two-time correlators in systems with dynamical exponent , and validates these predictions through tests on several exactly solvable ageing models.
This paper derives the generic scaling forms of single-time and two-time correlators in non-equilibrium phase-ordering kinetics with dynamic exponent by establishing a new non-equilibrium representation of the Schrödinger algebra and utilizing the covariance of four-point response functions.
