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 derives a universal, closed-form expression for the dynamical Love numbers of Schwarzschild black holes to all orders in gravity for any spin and multipole, revealing that the response factorizes into horizon absorption, near-zone running, and a far-zone dressed logarithm containing a universal tower of Riemann zeta values, a result independently verified via shell effective field theory up to .
This paper constructs an infinite set of exact, gauge-invariant Dirac observables for Gowdy cosmologies that remain regular at the big bang singularity and systematically connect the full nonlinear gravitational dynamics to a simpler Carroll-type gravity theory through an anti-Newtonian expansion.
Using the EAdS reformulation of the in-in formalism, this paper analytically computes one-loop gauge-field corrections in scalar QED on dS to demonstrate how electric screening induces an anomalous dimension for the boundary current and shifts the Dirichlet photon into a dS resonance (quasinormal mode), while establishing a spectral Cutkosky rule that connects the kernel's discontinuity to on-shell two-particle cuts.
This paper demonstrates that the imaginary part of holographic timelike entanglement entropy serves as a non-local quantum-information probe for criticality in strongly coupled charged systems, exhibiting a characteristic inverse-square-root divergence in its derivative at the critical point that signals the emergence of maximal quantum coherence between initial and final states.
This paper provides detailed algebraic proofs for two specific giant graviton expansions of supersymmetric indices in four-dimensional super-Yang--Mills theory, utilizing Hall--Littlewood orthogonality and free-fermion factorization, while clarifying the scope and limitations regarding the full three-species expansion.
The author constructs a three-parameter family of regular analytic supergravity solutions, derived from a consistent truncation of type IIB supergravity, which are holographically dual to the gauge theory on a four-sphere and -invariant Janus interfaces in SYM.
This paper extends hydrodynamic effective field theory to out-of-time-order correlators by employing a four-fold time contour and local SL(2,R) symmetry, successfully deriving transport coefficients from the SYK lattice model to demonstrate that hydrodynamic universality governs scrambling and saturates the chaos bound.
This paper utilizes the Feynman-Vernon influence functional to demonstrate that parametric resonance in a system of two quadratically-coupled harmonic oscillators triggers a runaway growth of quantum entanglement and a rapid breakdown of perturbation theory, thereby highlighting critical limitations of the semiclassical approximation in coupled quantum-classical systems.
This paper provides a microscopic derivation of the semi-classical entropy for regular BTZ black holes in 3d Lovelock gravity with an infinite tower of corrections by utilizing a mini-superspace formalism to compute soliton masses and verify the Cardy formula for both static and rotating configurations without relying on central charges.
This paper demonstrates that in a projective rotor model, the rank polarization of a collective order parameter toward a single dominant eigenline is logically independent of dynamical autonomy, as the authors construct rotationally invariant interactions that fix the equilibrium tensor while systematically suppressing transverse fluctuations to prove that spectral selection and infrared stability are distinct physical properties.
