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 introduces a helical generalization of the Sachdev-Ye-Kitaev model in 1+1 dimensions, demonstrating that while its full interaction space breaks exact solvability, the theory flows to a free and integrable fixed point in the infrared limit due to the marginal irrelevance of all interactions.
This paper constructs Hilbert spaces for minisuperspace quantum cosmology in the extreme slow-roll limit, demonstrating that fixing the potential energy yields a one-dimensional physical space favoring Vilenkin's tunnelling wavefunction, while allowing it to vary leads to an infinite-dimensional space where self-adjointness imposes boundary conditions that generally mix Hartle-Hawking and tunnelling wavefunctions, with a specific choice nearly recovering the Hartle-Hawking state.
This paper utilizes thermal inversion formulas to derive accurate asymptotic expressions for spectral densities and OPE coefficients of heavy operators in a 3D CFT dual to an interacting scalar field in AdS, demonstrating that these analytic results remain quantitatively reliable even at intermediate conformal weights despite bulk interactions.
This paper establishes a systematic thermodynamic framework based on potential representations to derive equations of state and response functions for ideal gases and Schwarzschild black holes in a spherical cavity, revealing that the quasi-local black hole's stability and thermodynamic behavior critically depend on the specific representation and fixed variables chosen.
This paper establishes that Casimir energies in nonlinear scalar and electromagnetic theories can be accurately computed using an effective-metric prescription derived from the Hessian of the Lagrangian or fluctuation branches, a method validated by exact agreement between direct mode summation and the effective-metric formula for nonlinear electrodynamics in a constant magnetic background.
This paper investigates the shadow, strong-field lensing, and emission properties of static, spherically symmetric dilatonic black holes, demonstrating that increasing charge and dilatonic coupling reduces the shadow size and using these findings to constrain model parameters against observational data from M87* and SgrA*.
This paper demonstrates that a pre-geometric gravity framework based on a Yang–Mills-like gauge formulation with spontaneous symmetry breaking can consistently generate the effective metric and classical dynamics underlying the Geometric Trinity of Gravity, thereby unifying General Relativity, Teleparallel Gravity, and Symmetric Teleparallel Gravity as different manifestations of a single pre-geometric origin.
This paper presents a first direct regularized construction of the unprojected sectors of the Type IIB Superstring torus vacuum by developing sector-resolved modular integrals using an -prescription and -regularization framework, which is subsequently cross-checked via Lorentzian-inversion reconstruction.
This paper demonstrates that semiclassical entanglement entropy in a driven 2D CFT encodes its dynamical phases and, through a holographic dual calculation of backreacted geometry, provides a nontrivial verification of the Faulkner-Lewkowycz-Maldacena conjecture at the first quantum correction order.
This paper proposes a classical Hamiltonian formalism for plasmon bremsstrahlung in a hot quark-gluon plasma by generalizing the Lie-Poisson bracket to include non-Abelian color charges and deriving a self-consistent system of kinetic equations to describe the time evolution of plasmon number densities and hard particle color charges.
