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 argues that near the surface of an Exotic Compact Object, the vacuum Einstein equations induce chaotic metric oscillations analogous to cosmic billiards, where sign-changing potential walls cause compact directions to collapse into zero size, naturally transitioning the geometry into the interior of string theory fuzzballs.
This paper aims to bridge a gap in pedagogical literature by demonstrating the application of the Hamilton-Ostrogradski formalism to the Pais-Uhlenbeck oscillator and coupled oscillators, providing a foundation for advanced classical mechanics courses.
This paper proposes a hidden-sector dark matter model where the dark matter and Standard Model decouple at high temperatures yet evolve to similar temperatures at freeze-out, allowing for the observed relic abundance with standard annihilation cross sections while rendering direct detection and collider signals potentially unobservable due to extremely weak couplings.
This paper proves that a non-trivial quantum Yang-Mills theory must possess a mass gap arising from a constant tadpole term in the gluon self-energy, a conclusion derived from a novel constraint on QCD solutions within the Slavnov-Taylor identity framework that preserves perturbative renormalizability while addressing the Jaffe-Witten theorem.
This paper investigates the Dynamical Casimir Effect for a real scalar field in dimensions interacting with a time-dependent Dirichlet surface by employing a perturbative expansion up to fourth order to derive general expressions for pair creation probabilities and analyze the influences of space-time dimensionality and non-linear effects.
This paper utilizes effective field theory consistency relations to demonstrate that current constraints on the effective gravitational constant derived from gravitational wave observations are consistent with, and in the case of GW170817 comparable to, those obtained from large-scale structure surveys, thereby validating these independent probes of dark energy.
This paper presents a universal improvement to the Robertson-Schrödinger uncertainty relation by introducing a new, experimentally accessible noncommutativity-induced term that tightens the bound for mixed states and becomes an exact equality for all states and observables in two-level quantum systems.
This paper demonstrates that autoregressive neural networks can efficiently estimate reduced density matrices and calculate the continuum limit of bipartite entanglement entropies for quantum spin chains by leveraging their correspondence with classical two-dimensional systems, requiring only a single training session for a fixed discretization and volume.
This paper establishes a direct link between spread complexity and quantum circuit complexity by demonstrating that the former emerges as a limiting case of a synthesis framework involving time-evolution and superposition, offering a physical interpretation and computational advantages over traditional methods like the Lanczos algorithm.
This paper introduces a real-time Wigner-functional lattice framework with a connected-cluster survival criterion to accurately characterize false-vacuum decay rates across the quantum-to-thermal crossover, revealing that global-survival methods can underestimate rates at high temperatures due to multi-seed dynamics while transient effects contaminate fraction observables at low temperatures.
