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 study utilizes a second-order relativistic viscous hydrodynamic framework to quantify the contributions of thermal vorticity and evolving magnetic fields to the global spin polarization of hyperons, finding qualitative agreement with recent ALICE measurements at TeV energies and offering new insights into the vortical structure of QCD matter.
This paper extends the concepts of hidden zeros and $2$-split from tree-level to loop-level Feynman integrands in the model by utilizing a shuffle permutation factorization mechanism to derive remarkably simple kinematic conditions and a generalized $2$-split formula that expresses the -loop integrand as a sum of terms.
This paper demonstrates that one-loop corrections from torsion-induced four-fermion interactions can significantly suppress the stochastic gravitational-wave signal from inflaton decay by up to two orders of magnitude, potentially rendering it undetectable by future experiments despite only modest enhancements.
This paper presents a robust, deep-learning-based amortized inference framework for the Taiji space-based gravitational-wave detector that combines conditional normalizing flows, time-frequency contrastive learning, and a neural glitch generator to achieve accurate and well-calibrated parameter estimation for massive black hole binaries even in the presence of transient noise artifacts.
This paper demonstrates that bipartite entanglement harvesting from a quantum vacuum using multiple Unruh-DeWitt detectors can be efficiently analyzed via a linearly scaling submatrix, revealing that increasing the number of detectors not only maximizes harvested entanglement in specific configurations but also broadens the operational ranges for energy gaps and separations.
This paper demonstrates that the analytic part of the stress-energy tensor's asymptotic expansion at thermodynamic equilibrium in curved spacetime is universal across various geometries and quantum field theories, depending solely on covariant derivatives of the Killing four-temperature and metric tensor, while non-universal contributions arise from non-analytic terms linked to specific boundary conditions or global spacetime properties.
This paper investigates charged black hole solutions in non-linear electrodynamics, demonstrating that their non-monotonic lapse functions enable stable light-rings and static near-horizon observers, which in turn generate additional, longer-lived quasinormal mode branches despite being screened from distant observers.
This paper extends Kollár's result on the preservation of elliptic fibrations under small deformations to general fibered smooth K-torsion varieties with vanishing second cohomology of the structure sheaf, utilizing Hodge theory and the Kawamata–Ran -lifting criterion to further establish that semiample line bundles remain semiample up to homological equivalence even without this cohomological assumption.
This paper demonstrates that merons, key topological solitons in Yang-Mills theory, are universal across a broad class of non-Abelian gauge theories and, when including gravitational backreaction, yield regular black hole and Euclidean wormhole solutions that resolve singularities while preserving intrinsic effects like spin from isospin.
This paper employs variational Monte Carlo with neural quantum states to characterize physical states of 4D Euclidean loop quantum gravity on a complete graph, revealing distinct solution families for the Hamiltonian constraint and its adjoint that correspond to the Ashtekar-Lewandowski and Dittrich-Geiller vacua, respectively, while also providing insights into their relationship with continuum solutions.
