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.
By consistently applying the gravitational path integral to compute both amplitudes and normalization norms, this paper demonstrates that the Hartle-Hawking no-boundary proposal predicts probabilities of nearly or exactly one for closed universes, implying that all relevant cosmological states are effectively parallel to the Hartle-Hawking state.
This paper investigates entanglement entropy in the string theory from both target space and matrix model perspectives, arguing for a generalized entropy formula that includes a dilaton-dependent gravitational area term and demonstrating that the standard leg-pole transformation cannot account for this term, suggesting its origin lies in non-singlet sectors.
This paper numerically investigates the time evolution of sound modes in a Bjorken-expanding Super-Yang-Mills plasma, revealing how longitudinal expansion-induced anisotropy splits the speed of sound into two distinct values and constructing an anisotropic hydrodynamic framework to interpret these findings for heavy-ion collision data.
This paper proposes an equatorial projection framework that refines meromorphic 2D CFTs by encoding genus-one couplings via modular-invariant matrices, demonstrating how Verlinde lines and anyon-permuting defects act on commutant pairs within the theory to generate new modular-invariant non-meromorphic theories beyond the landscape.
This paper analytically solves the modified Dirac equation for Majorana neutrinos with transition magnetic moments in a magnetic field using a wave packet formalism to derive oscillation probabilities and demonstrate that decoherence effects, which depend on the relative strengths of vacuum and magnetic frequencies, can occur during propagation in supernova magnetic fields.
This paper provides a pedagogical introduction to the AdS/CFT correspondence, covering its physical motivation, foundational concepts, consistency checks, and recent extensions to de Sitter and flat spacetimes.
This paper utilizes the observed 11.24-year jet precession period of M87* within the Kerr-Bertotti-Robinson spacetime to derive a stringent, shadow-independent upper bound on the black hole's magnetic field strength (), demonstrating that jet precession serves as a robust probe for magnetized black holes in strong gravity.
This paper employs the island paradigm to demonstrate that Kerr-AdS black holes exhibit a unitary Page curve that transitions from linear growth to a constant value, while revealing that first-order phase transitions induce sharp discontinuities in the curve across different thermodynamic ensembles.
This paper establishes an alternative definition of the celestial Mellin transform to derive a celestial dispersion relation and defines the celestial Regge limit, thereby connecting celestial CFT data to the partial amplitudes of bulk Regge scattering.
This pedagogical review outlines a method for automatically calculating and resumming Feynman diagrams in quantum nanoelectronics using matrix product states and the Tensor Cross Interpolation algorithm, specifically applied to the non-equilibrium Kondo effect in the single impurity Anderson model.
