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 that interactions between gravitons and inflatons during the inflationary period, combined with horizon-induced "which-path" information, generate entangled graviton states that produce a measurable quantum signature in the scalar four-point correlation function, potentially observable through high-order galaxy correlations like halo bias and intrinsic alignment.
This paper proposes a method to test the quantum origin of primordial fluctuations by constructing a Bell inequality from the eight-point correlation function of scalar curvature perturbations, which encodes polarization entanglement from pairs of gravitons generated during inflation.
This paper demonstrates that relational observables in quantum gravity can be expressed as dressed operators, revealing that the algebraic structure of quasi-de Sitter space corresponds to a Type II von Neumann algebra due to isometry breaking, which fundamentally distinguishes it from the Type II algebra of de Sitter space.
This paper formulates the Gao-Jafferis-Wall traversable wormhole protocol as a quantum channel, demonstrating that its capacity is determined by the time derivative of out-of-time-ordered correlators (reflecting operator size growth) and is bounded by Einstein gravity limits, thereby establishing a benchmark for quantum simulations.
This paper establishes that any non-quantized model of gravity consistent with Galilean invariance and Newtonian averages must introduce a quantifiable minimum level of noise, implying that observing gravity below this noise threshold would experimentally prove its ability to entangle massive objects and thus its quantization.
This paper demonstrates that topological surface states, modeled via axion electrodynamics, mediate measurable modifications to classical electromagnetic radiation from sources near an interface, resulting in azimuthal symmetry breaking for antennas and a specific intensity reduction for accelerated charges due to interference with image magnetic monopoles.
This paper presents ongoing lattice studies of two-dimensional maximally supersymmetric Yang-Mills theory, including the construction of a supersymmetry-preserving lattice action and the development of new simulation routines, to facilitate numerical tests of gauge-gravity duality and explore non-perturbative phenomena.
This paper presents a new method for explicitly constructing complete sets of fields in Calabi-Yau orbifold models by leveraging the connection to exactly solvable superconformal field theories, utilizing spectral flow twisting and the requirement of mutual locality.
This paper demonstrates that Calabi-Yau orbifolds constructed from products of N=(2,2) supersymmetric minimal models form canonical mirror pairs of isomorphic models by utilizing spectral flow constructions associated with mutually dual Berglund-Hubsh-Krawitz groups.
Motivated by conformal bootstrap principles and space-time supersymmetry, this paper presents a new method for constructing Gepner model orbifolds by utilizing spectral flow generators to define an admissible group and its mirror counterpart, thereby generating modular invariant models with mutually local physical fields.
