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.

This paper identifies the internal low-energy symmetry of two-dimensional quadratic-band-touching Hamiltonians as the unitary symplectic group $USp(2N)$, constructs the corresponding rotationally invariant interacting theory, and demonstrates that for lattice systems like honeycomb, this symmetry reduces to the unitary group through the intersection of symplectic and orthogonal symmetries.
This paper proposes a model of fermion condensate inflation driven by spacetime torsion that eliminates the need for new scalar fields, utilizes an axial chemical potential to trigger a dynamical waterfall mechanism and instant preheating, and generates primordial black holes from Q-ball seeds within a parity-violating Chern-Simons gravity framework.
This paper proposes a model in 2+1 dimensions where the black hole horizon is composed of quantized elementary lengths, enabling a length ensemble formulation that directly derives the Hawking black body spectrum and its modified temperature for a local observer via the Tolman factor.
This paper investigates how gravitational inhomogeneity affects transport phenomena in a system of massless Dirac fermions coupled to both Maxwell and dark photon fields, revealing that the resulting currents are proportional to beta functions and predicting specific corrections to scale conductivities in both the visible and dark sectors.
This paper investigates the infrared behavior of one-loop complex saddles in 4D Lorentzian Einstein-Hilbert gravity by computing the renormalized Hartle-Hawking wavefunction under Dirichlet and fixed extrinsic curvature boundary conditions, revealing that metric fluctuations induce secularly growing infrared divergences similar to those in pure Lorentzian de Sitter space, while confirming that all considered saddles remain KSW-allowed.
This paper presents the RLL-realization of extended orthosymplectic quantum supergroups for any parity sequence using previously evaluated R-matrices, while establishing their compatibility with generalized doubles, relating sign conventions via 2-cocycle twists, and proving a factorization of the reduced R-matrix.
This paper demonstrates that a quantum system comprising a harmonic oscillator polynomially coupled to a ghost with negative kinetic energy can be consistently quantized with a well-defined vacuum and manifestly unitary evolution, provided the system possesses an integral of motion with a positive discrete spectrum that ensures stability despite the Hamiltonian's unbounded spectrum.
This paper demonstrates that quantized integrable systems with opposite-sign kinetic terms (ghosts) can possess discrete, non-dense energy spectra with specific accumulation properties, thereby refuting the common belief that such ghostly systems must necessarily exhibit continuous or dense energy spectra.
This paper derives the theoretical framework for high-energy photon holograms of a photon gas, including explicit expressions for various quantum states and dielectric susceptibilities, and demonstrates that such holograms are measurable with existing experimental facilities under specific high-energy conditions.
