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 establishes quantitative criteria for the validity of classical evolution in inflationary cosmological perturbations by analyzing Keldysh contributions to the bispectrum, demonstrating that non-linear interactions can be accurately described by classical dynamics even before horizon crossing and providing a rigorous foundation for using stochastic inflation to approximate full quantum evolution.
This paper demonstrates that realistic, fully non-linear Numerical Relativity simulations of cosmological inflation can be achieved by initializing stochastic Bunch-Davies vacuum conditions that satisfy General Relativity constraints, successfully recovering standard perturbative results while capturing strongly non-linear inhomogeneities in complex models like strong resonance.
This paper establishes a framework for cohomological Hall algebras associated with coherent sheaves supported on a fixed curve within a smooth surface, constructing a generalized moduli stack and defining a functorial algebra that depends only on the formal neighborhood of the curve to study Hecke operators and resolve questions regarding Kleinian singularities.
This paper investigates how improvement ambiguities in the energy-momentum tensor affect Zamolodchikov's c-function in non-compact conformal field theories, revealing that while the c-function can become unbounded and non-monotonic due to IR divergences, a specific sum rule proposed by Hartman and Mathys remains robust and correctly yields the effective Virasoro central charge when the IR theory is gapped.
This paper demonstrates that four-dimensional de Sitter vacuum solutions can be realized on probe D3 and D5 branes nucleated in an asymptotically background by leveraging stringy corrections, high chemical potentials, and specific gauge field configurations without the need for fine-tuning.
This paper determines the group of holomorphic symplectic automorphisms for -orbifold limits of K3 surfaces and embeds this group into the Mathieu groups and by adapting lattice techniques to track these symmetries within the broader context of Mathieu moonshine.
This paper investigates how the fusion 2-category symmetry of a fermionic (2+1)d quantum field theory is modified when stacking with topological field theories, specifically , is treated as an equivalence relation, revealing a finite set of inequivalent symmetry modifications linked to minimal nondegenerate extensions and tangential structures.
This paper demonstrates that the standard Lindblad master equation fails to reproduce the non-exponential, Gaussian decay of purity and coherences observed in exact unitary dynamics of a many-body open quantum system, highlighting a fundamental limitation of Markovian approximations with constant coefficients in realistic settings.
This paper utilizes the fluid/gravity correspondence within the AdS/BCFT framework to demonstrate that specific metric boundary conditions on an end-of-the-world brane naturally induce corresponding boundary conditions for the velocity and temperature fields of conformal fluids in the dual boundary conformal field theory.
This paper investigates the role of the QCD scale anomaly in the nucleon's gravitational form factors using a scale-invariant Skyrme model, demonstrating that the inclusion of a scalar meson to represent gluonic contributions is crucial for satisfying nucleon stability conditions and accurately reproducing lattice QCD results for the form factor.
