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 demonstrates that negative energy flux emitted by a moving mirror with non-monotonic acceleration serves as a channel for information recovery, thereby enhancing the bipartite entanglement accessible to detector modes in analog Hawking radiation.
This paper presents a formulation of quantum field theory entirely based on real numbers by replacing the imaginary unit with a specific 2x2 matrix, demonstrating that this "real" framework yields physically equivalent predictions to standard complex quantum field theory while offering a new ortho-symplectic perspective on the Standard Model and potential pathways to new physics through J-symmetry breaking.
This paper demonstrates that purported weak-field solutions to Conformal Gravity proposed by several authors are erroneous because they incorrectly rely on second-order Poisson equations instead of the required fourth-order field equations, while also highlighting additional inconsistencies in their derivations.
This paper demonstrates that the physical procedure of "gauging the gauge" corresponds mathematically to categorification, generating higher-gauge theories based on crossed-modules that can resolve anomalies in quantum field theory by absorbing curvature defects.
This paper investigates the non-relativistic limit of HSZ theory, demonstrating that while the Lagrangian remains convergent to all orders in derivatives, the metric corrections cannot be fully trivialized, thereby providing a non-relativistic truncation of the four-derivative structure of heterotic supergravity.
This paper demonstrates that in a BRST-invariant quantization of General Relativity, the bulk Hamiltonian can be expressed as a BRST-exact operator (the anticommutator of the BRST charge and the temporal ghost field), which governs time-reparameterization of physical observables without trivializing the time evolution of gravitational backgrounds or scattering amplitudes.
This paper numerically demonstrates that while spontaneous baryogenesis exhibits a cubic dependence of baryon asymmetry on the initial misalignment angle for small values, this scaling breaks down and particle production saturates as the angle approaches in Minkowski spacetime.
This paper formulates an in-in framework for strong-field QED pair creation using worldline propagators, demonstrating that in-in corrections to in-out quantities correspond to non-local interaction terms and providing an exact first-quantized definition for the creation of N-pairs through the resummation of the partition function.
This paper presents a unified computational framework using algebraic geometry and numerical topology to analyze the vacuum structure of 4-charge extremal black holes in Type IIA string theory, successfully reproducing BPS degeneracies for specific D-brane configurations and demonstrating the absence of zero-energy ground states in non-BPS systems through advanced topological regularization techniques.
This paper establishes that changing the initial state in Krylov complexity corresponds to a Christoffel transform of the underlying spectral measure, providing a unified framework to analyze state reorganization, amplitude jumps, and complexity finiteness across various quantum systems through orthogonal polynomial recurrences and kernel projections.
