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 presents a simple general relativity model coupled to a constrained scalar triplet and a non-propagating three-form sector that yields a continuous family of asymptotically flat, geometrically regular black holes with topological hedgehog scalar hair, a de Sitter core, and Schwarzschild-like asymptotic behavior corrected only at order .
This paper computes the efficiency of reversible Stirling engines across diverse working substances, identifying that regeneration can drive the efficiency toward the Carnot limit when the fixed-volume heat capacity is volume-independent, while demonstrating that for holographic CFTs dual to AdS black holes, the efficiency asymptotically approaches the Carnot value in the large-potential limit.
This paper demonstrates that an emergent, non-invertible gauge symmetry arises within specific sectors of a fragmented dipole-conserving spin chain, enabling the exact quantum simulation of a gauge theory using a non-gauge-invariant Hamiltonian.
Using a non-relativistic quark model with a harmonic oscillator potential, this paper investigates how neutral and charged mesons behave in magnetic fields across weak to strong regimes, highlighting distinct differences in their transverse dynamics and demonstrating how zero-point energy stabilizes high-spin charged mesons by canceling orbital Zeeman effects.
This paper presents an exact analytical and numerical study of a boost-invariant, out-of-equilibrium fluid of non-interacting Dirac fermions with finite spin potential, deriving explicit expressions for thermodynamic quantities and demonstrating that non-vanishing spin polarization in such free systems arises solely from the spin potential while shear-induced polarization and the spin Hall effect are absent.
This paper demonstrates that a minimal two-field scalar-tensor completion of Starobinsky inflation remains robust against radiative deformations, as nearby trajectories converge to an attractor where suppressed entropy modes preserve the model's characteristic Starobinsky-like observational predictions.
This paper quantitatively evaluates saddle-point expansion methods for testing self-dualities in 1+1 dimensional critical scalar theory, finding that while they accurately predict free energy, they deviate by approximately 25% from the peak location of the correlation length.
This paper investigates the Coulomb potential within a combined Podolsky and Carroll-Field-Jackiw electrodynamics framework, demonstrating that while the Podolsky term regularizes short-distance divergences, the Lorentz-violating CFJ background can reintroduce these divergences and significantly alter the interaction potential through both spatial anisotropy and timelike dispersion effects.
This paper establishes that global geometric relations among nodes in multi-node conifold degenerations constrain the realized extension classes to a specific subspace, unifying the perverse-sheaf, mixed-Hodge-module, and categorical descriptions of these degenerations with their resolution and smoothing counterparts.
This paper demonstrates that the previously proposed thermodynamic interpretation of scalar-tensor gravity, which attributes a non-zero temperature to departures from general relativity, is not frame-invariant, and instead establishes a frame-invariant formulation where the effective fluid is perfect with zero temperature, identifying a frame-invariant chemical potential as the true driver of deviations from general relativity.
