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 proposes and validates via lattice simulations a novel Grand Unified Theory-scale first-order phase transition within Starobinsky inflation, featuring a dynamically evolving potential barrier that suppresses early bubble nucleation while triggering massive nucleation at the end of inflation to successfully resolve the graceful exit problem and produce a distinctive gravitational-wave spectrum.
This paper proposes a holographic framework for fermionic 3D gravity in AdS, demonstrating that summing over spin structures and incorporating topological field theories yields spectral statistics consistent with fermionic 2D CFT anomalies and a newly defined random matrix theory (RMT) that accommodates fermionic spectra.
This paper establishes a bidirectional mapping between causal models and tensor networks to derive the direction of time and causal structure from operational principles, thereby clarifying causal influence in tensor networks and enabling the analysis of emergent causal structures in holographic settings.
This paper employs a point particle Effective Field Theory (EFT) approach, matched with Black Hole Perturbation Theory results calculated via the Mano-Suzuki-Takasugi method, to systematically derive Next-to-Next-to Leading Order dynamical tidal Love numbers and their Renormalization Group equations for non-viscous neutron stars, including those admixed with bosonic or fermionic dark matter.
This paper demonstrates that spacetime curvature within a five-dimensional dilaton-gravity system can classically stabilize black strings extending from a flat brane to a timelike boundary, even in cases where the strings possess infinite horizon area.
This paper presents a hybrid method combining machine learning, analytic ansätze, and symbolic regression to construct approximate closed-form expressions for Ricci-flat Kähler metrics on Calabi-Yau threefolds that explicitly depend on Kähler moduli, successfully demonstrating percent-level accuracy for two specific examples with .
This paper investigates entanglement harvesting between two qubits coupled to a massless scalar field in the Minkowski vacuum, where one qubit is inertial and the other undergoes uniform circular motion, analyzing how the radius and angular velocity of the rotating qubit influence the generation of entanglement and mutual information.
This paper argues that time-reversal in de Sitter space is a spontaneously broken gauge symmetry of the bulk, evidenced by a specific holonomy that flips the direction of time along closed curves, thereby reconciling conflicting views from Harlow and Witten.
This paper computes the vacuum expectation value of the stress-energy tensor for a scalar field on a product spacetime consisting of an FLRW background and a time-dependent compact dimension by modifying the adiabatic regularization prescription to derive analytic expressions that recover known Casimir and FLRW results in specific limits.
This paper establishes a fully relativistic framework for slowly rotating two-fluid neutron stars that reveals intrinsic collective rotational eigenmodes and demonstrates that the preservation or breakdown of rotational-tidal universality depends on dark-sector microphysics rather than simply the presence of an additional gravitationally coupled component.
