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 presents the first explicit construction of large-scale, gauge-invariant phase-space variables and the corresponding quadratic and cubic Hamiltonians for multifield inflation at second-order perturbation theory, demonstrating their consistency with standard gauge-fixed results and providing a framework for extending these calculations to higher orders.
This paper demonstrates that the standard quantum statistical relation for black hole thermodynamics fails for charged magnetic black holes in five-dimensional Einstein-Maxwell-Chern-Simons theory unless the Euclidean action is completed with a nonlocal radial integral to form a strictly gauge-invariant transgression form, which is necessary to restore thermodynamic consistency and the first law.
This paper demonstrates that the exact renormalization group flow of density matrices in quantum field theory is governed by a Lindblad master equation, where dissipative terms drive the correct coupling flow and ensure that state distinguishability serves as a renormalization group monotone via the data processing inequality.
This paper investigates higher-point correlators in the non-conformal BFSS matrix model using Witten diagrams and amplitude techniques, demonstrating that the added complexity is minimal and providing new targets for future Monte-Carlo and quantum simulations through the computation of a leading three-point diagram in the squeezed limit.
This paper demonstrates that the requirement for target spacetime to admit a spin structure in Type II string theory arises directly from the consistency of the worldsheet GSO projection, which is governed by a mixed global anomaly detected by spin bordism groups, while also classifying all corresponding theta angles as target space background fields.
Based on -body simulations showing that orbital velocity increases linearly over time, this paper conjectures a crude upper mass limit of approximately for supermassive black holes in the current universe, beyond which equal-mass binaries would fail to coalesce within the age of the universe.
This paper establishes the spectral foundation for mapping bilocal Cooper pairing fluctuations in the Yukawa-SYK model to a scalar field in AdS by demonstrating that the superconducting instability resides exclusively in the continuous scattering sector of the associated dS Laplacian, thereby providing the missing microscopic justification for the holographic projection.
This paper establishes that the Contact 3-Structure-induced transverse -structure in the finite- thermal -theory dual of QCD-like theories belongs to the symplectic nearly half-flat class, thereby completing its -structure classification and providing a top-down holographic mechanism for generating weak magnetic fields through Kaluza-Klein reduction.
This paper presents a worldline effective field theory framework to compute gravitational Compton scattering amplitudes to all orders in Newton's constant, yielding results up to that reveal a first ultraviolet divergence at that order, demonstrate the vanishing of static Love numbers for Schwarzschild black holes, and predict new subleading non-zero Love numbers.
This paper introduces a vortex-impurity model where specific nonlocalized impurities enable the description of vortex-antivortex annihilation and the generation of symmetric pairs through BPS equations mapped to the impurity-free Abelian-Higgs model, allowing for the analysis of their dynamics via moduli-space geodesics.
