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 introduces an index-based tensorial framework that leverages the additivity of weights to provide a practical method for computing charge eigenvalues of arbitrary tensor representations in unitary gauge groups, with explicit applications demonstrated for SU(2), SU(3), and SU(5).
This paper demonstrates that LIGO's constraints on the gravitational wave background rule out the formation of Planck star relics as dark matter from Gaussian initial conditions, leaving non-Gaussian primordial fluctuations as the sole viable formation channel.
This paper presents an exact solution for the entanglement entropy dynamics following a quench from a thermal pure quantum state in a free fermion system, revealing a characteristic double-plateau structure that contrasts with typical linear growth and saturation, as confirmed through 2D conformal field theory on the Klein bottle, matrix Riccati equation numerics, and a quasiparticle picture.
This paper explores the cosmological consequences of the Thermodynamic Split Conjecture, demonstrating that the inequivalence between black hole and cosmological horizon thermodynamics can alter key early and late-universe phenomena while offering potential resolutions to the and tensions through modified Friedmann dynamics.
This paper employs a expansion to construct a Fierz-complete renormalizable Lagrangian for the Gross--Neveu model, demonstrating that the symmetric-tensor and adjoint-nematic fixed points remain critical for and clarifying the nature of the spontaneous symmetry breaking of down to .
This paper proposes novel Solar System-scale searches for Primordial Black Holes, demonstrating that asteroid-to-dwarf-planet mass PBHs could be detected via pulsar timing array signatures and planetary mass PBHs via accretion flares from Kuiper Belt interactions, thereby opening a new observational frontier for mass ranges unconstrained by conventional cosmological methods.
This paper introduces a minimal-control protocol that generates unitary -designs by evolving a system under a random Hamiltonian and performing a single quench to an independent Hamiltonian after the Thouless time, thereby breaking residual spectral correlations to achieve Haar-like randomness with significantly fewer operations than existing methods.
This paper proposes "Cosmological Teleodynamics," a game-theoretic statistical framework that reinterprets dark energy, dark matter, and cosmological tensions as emergent phenomena arising from the Universe's intrinsic nonlocal memory and systemic organization, thereby offering a unified, particle-free alternative to the standard dark sector.
This paper demonstrates that moving a point charge near a spherical topological insulator induces a rotation of the sphere around the symmetry axis connecting the charge and the sphere's center, a phenomenon driven by axion electrodynamics that allows for the derivation of an exact expression for the surface electronic velocity.
This paper presents experimental predictions of a local scale-invariant, non-Hermitian pilot-wave formulation of quantum theory, demonstrating that while minute scale effects are typically hidden, they could be detected in specific Aharonov-Bohm and spectral experiments, while simultaneously resolving Einstein's historical objections regarding the second-clock effect and distinguishing the theory from other quantum formulations through trajectory-dependent probabilities.
