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 constructs a unitary extended -dimensional toral Chern-Simons TQFT with gauge group using geometric quantization in real polarization, demonstrating how the finite discriminant group governs the state spaces and recovers bosonic Abelian topological order at genus one.
This paper identifies universal non-Gaussian signatures in the inflationary bispectrum arising from transient tachyonic instabilities of entropic fluctuations, demonstrating that exact numerical calculations reveal distinctive features like magnified folded configurations and tachyonic resonances that cannot be fully captured by single-field effective descriptions, while providing new templates for observational constraints on non-geodesic inflationary attractors.
This paper develops a contraction theory for universal -matrices of quantum groups to derive a new (1+1) centrally extended quantum Poincaré algebra whose dual form naturally describes relativistic quantum reference frame transformations and contracts to the known Galilei -matrix for non-relativistic frames.
This paper investigates the thermodynamics, photon sphere, shadow, and dynamical stability of an AdS Ayón-Beato-García massive black hole, revealing how graviton mass and magnetic charge influence its Gibbs free energy, shadow radius, and quasinormal modes while confirming its overall stability.
This paper initiates a program to investigate the ultraviolet completion of generalised Proca theories within the asymptotic safety paradigm, identifying non-perturbative fixed points that demonstrate the renormalisability of vector-tensor theories and constrain viable late-time cosmological scenarios.
This paper demonstrates that tree-level cosmological wavefunctions in theories are uniquely determined by locality and a newly discovered set of hidden zeros that enforce a dual "shuffle" factorization principle, thereby extending on-shell methods and the zeros-BCFW correspondence from flat-space scattering amplitudes to cosmology.
This paper demonstrates that spontaneous symmetry breaking can persist up to arbitrarily high temperatures in four-dimensional ultraviolet-complete quantum field theories by identifying explicit finite- benchmark models where a negative thermal mass prevents symmetry restoration despite asymptotic freedom.
This paper constructs 3+1D and 2+1D Hamiltonian lattice models for Weyl fermions and Dirac cones that evade no-go theorems by utilizing exact, not-on-site chiral symmetries—specifically a Ginsparg-Wilson analog and an Onsager algebra—to protect gaplessness and generate global anomalies even in the absence of crystalline translations.
This paper applies an ADM deparametrization strategy to radial canonical gravity in three dimensions to clarify holographic interpretations through identified radial 'volume time' and 'true' degrees of freedom, while also discussing York time, conformal boundary conditions, and constructing a BTZ wavepacket solution to the radial Wheeler-DeWitt equation.
This paper establishes a quantum energy inequality for non-commutative quantum field theories by constructing deformed operator combinations that provide a rigorous lower bound on averaged energy density, thereby ensuring the theory's stability and physical consistency.
