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 proposes a cosmological model satisfying the Covariant Entropy Bound where early-universe tiny black holes decay to generate the radiation-dominated era and CMB observations, while a distribution of larger primordial black holes and their Planck-scale remnants account for dark matter and the formation of early galaxies observed by the James Webb Space Telescope.
This review article introduces the fuzzy sphere regularization method as an efficient tool for studying 3D conformal field theories and critical phenomena, highlighting its unique ability to reveal deep connections between noncommutative geometry, the quantum Hall effect, and the state-operator correspondence on the geometry.
This paper employs the worldline formalism and geometric quantization to construct a Hilbert space of Virasoro conformal blocks for matter coupled to 3D Einstein gravity, successfully reproducing the known one-loop partition function on thermal AdS and conjecturing its all-orders value via equivariant localization.
This paper initiates the study of networks connecting 10d heterotic string theories via cobordism-motivated junctions, generalizing worldsheet descriptions to construct arbitrary graph-based networks, analyze higher-dimensional bubble nucleations, and define novel compactifications where different sectors propagate on distinct compact spaces.
This paper resolves long-standing ambiguities in chiral spin liquid theory by deriving an exact finite-size formula for parity-odd transport that proves corrections are strictly exponential, thereby establishing a precise, parameter-free quantitative link between microscopic spinon topology and observable fractional spin Hall conductance, which is validated through both exact band-structure calculations and density-matrix renormalization group simulations on the kagome lattice.
This paper proposes that the Krylov basis provides a semiclassical representation for complex many-body systems by demonstrating that Wigner negativity, a measure of classical simulation complexity, remains constant or grows slowly in various solvable models, thereby indicating emergent semiclassicality in Krylov space.
This paper presents a canonical quantization of Jackiw-Teitelboim gravity with finite Dirichlet boundaries by mapping its dynamics to a Pöschl-Teller scattering problem, yielding exact wavefunctions, a disk partition function with nonperturbative spectral corrections, and a UV completion that analytically extends the model into the black hole interior.
This paper demonstrates that in minimal-length quantum mechanics governed by the Generalized Uncertainty Principle, the standard equivalent characterizations of coherent states become inequivalent, leading to unique dynamical behaviors such as deformed phase-space trajectories and an intrinsic squeezing mechanism absent in ordinary quantum mechanics.
This paper derives a general formula for the Lamb shift of a static atom near a rotating planar surface, revealing that rotation induces two distinct contributions from orbital and spin angular momentum that modify the Casimir-Polder interaction and generate a finite linewidth signaling quantum friction.
This paper constructs five-dimensional rotating black holes in Einstein-Bumblebee gravity, demonstrating that while the Wald formalism and Komar integral yield different thermodynamic charges due to the Bumblebee coupling, the Kerr/CFT correspondence's microscopic entropy calculation precisely matches the Komar integral result rather than the Wald entropy.
