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 embedding the Klein-Gordon equation into a pair of coupled first-order equations to demonstrate the existence of two positive conserved quantities, thereby resolving the historical issue of negative probabilities without requiring quantum field theory and suggesting a relativistic framework where particle-antiparticle annihilation does not occur, offering a potential explanation for dark matter.
This paper computes the exact analytical inflationary trispectrum of primordial gauge fields arising from scalar and tensor exchanges in spectator models, revealing distinct momentum and angular dependencies that establish hierarchical relations with lower-order correlations and offer novel observational signatures for early-universe tensor interactions.
This paper presents updated observational constraints on the spatially flat CDM dynamical dark energy model using Planck 2018 and non-CMB data, finding that while the standard CDM model remains an excellent fit, current data mildly favor evolving quintessence-like dark energy and reveal tensions in the Hubble constant and CMB lensing amplitude that are partially alleviated by allowing the lensing consistency parameter to vary.
This paper demonstrates the robust emergence of Schrödinger symmetry in spherically-symmetric static mini-superspace models containing Maxwell and massless scalar fields through canonical transformations, identifying specific spacetime solutions and proposing a physical interpretation where symmetry generators either map solutions within a theory or generate new theories with transformed configurations.
This paper presents remarkably simple, dimension-independent covariant expressions for graviton and ghost propagators in Anti-de Sitter spacetime, achieved by selecting a special gauge-fixing condition that ensures improved infrared behavior and is unattainable in flat spacetime.
This paper demonstrates that the Symmetry Topological Field Theory (SymTFT) framework offers a natural and intuitive approach to defining entropic order parameters for phases with broken symmetries, including non-invertible ones, by revealing the information-theoretic origins of vacuum distinguishability through the exclusion of specific operators from observation.
This paper demonstrates that the nonlinear Schrödinger equation arising from the dual- deformed-derivative formalism can be transformed into a linear equation with a position-dependent mass, revealing that the deformation parameter effectively alters the system's geometry and modifies physical properties such as energy spectra and tunneling probabilities.
This paper investigates the thermodynamics of a Schwarzschild black hole within non-commutative gauge theory, demonstrating that non-commutative corrections remove temperature divergence, introduce logarithmic entropy corrections, and result in extremely sparse Hawking radiation that diverges as the black hole approaches the final stage of evaporation.
This paper constructs the phase space for an arbitrary cut of a null hypersurface in Minkowski spacetime and demonstrates its symplectomorphism to the infrared phase space of asymptotically flat gravity, explicitly mapping cut fluctuations to leading soft graviton modes and the supertranslation Goldstone mode to the product of the cut's size and its null time offset.
This paper demonstrates that in heavy local quenches within two-dimensional holographic conformal field theories, the time evolution of genuine tripartite entanglement is kinematically fixed by global saddle selection and winding mismatches in the bulk geometry, rather than by local energy responses or quasiparticle propagation.
