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 a manifestly covariant worldline action for both massive and massless particles in Minkowski and AdS spacetimes by deriving Hamiltonian constraints from the symplectic structure of coadjoint orbits associated with the Poincaré and AdS groups.
This paper generalizes the description of primordial gravitational waves from a two-mode to a three-mode Bogoliubov transformation, revealing that while large squeezing can render the universe classical if only two modes are considered, the full three-mode analysis preserves quantum characteristics via the quantum Poincaré sphere for any non-zero squeezing or non-zero coherent state components.
This paper demonstrates that naturalness scenarios naturally suppress neutrino masses through a mechanism involving numerous mixing partners, leading to a specific tower of additional neutrino mass eigenstates that offers unique, testable signatures in terrestrial oscillation, mass, and neutrinoless double beta decay experiments, thereby extending the model's phenomenological reach beyond cosmology.
This paper presents new exact charged black hole solutions in (2+1)-dimensional gravity using a cubic non-metricity model, revealing novel asymptotically Anti-de Sitter configurations that lack General Relativity counterparts, while analyzing their unique horizon structures, softened singularities, thermodynamic stability, and orbital dynamics.
This paper proposes a quantum simulation using an atom coupled to a bimodal optical cavity to emulate a (2+1)D massive gravity model, enabling the observation of spacetime metric fluctuations through the evolution of a fermion's spin with current technology.
This paper investigates the thermodynamic and optical properties of Einstein-Dyonic-ModMax black holes by incorporating Generalized Uncertainty Principle corrections and plasma effects, revealing that non-linear electrodynamics and quantum gravity modifications lead to stable remnants, frequency-dependent lensing signatures, and rich phase transition structures.
This paper generalizes spurion analysis to non-invertible fusion algebras, specifically near-group types like Fibonacci and Ising, by introducing a systematic labeling scheme for coupling constants that explains the radiative violation of tree-level selection rules and distinguishes these effects from those arising in lifted group symmetries.
This paper demonstrates that critical points between distinct, featureless bosonic atomic insulators in dimensions can host emergent conformally invariant quantum electrodynamics (QED) states, stabilized by lattice symmetries that suppress monopole proliferation, thereby revealing rich physics even in transitions between trivial phases.
This paper demonstrates that the holographic entanglement entropy of massive Chern-Simons fields in , calculated via the Faulkner-Lewkowycz-Maldacena formula with vanishing edge mode contributions, precisely matches the single-interval entanglement entropy of the dual primary operator and its descendants in large-charge CFTs, thereby resolving a discrepancy with earlier massless limit calculations.
This paper introduces a novel method using permutation defects between ground-state replicas to extract chiral topological properties, such as the chiral central charge and Hall conductance, directly from bulk wavefunctions, thereby bridging the gap between bulk entanglement measures and boundary anomalies for both numerical and quantum device applications.
