Nonlocal Fractional Quantum Field Theory and Converging Perturbation Series
Nikita A. Ignatyuk, Stanislav L. Ogarkov, Daniel V. Skliannyi
The main purpose of this paper is to derive a new perturbation theory (PT) that has converging series. Such series arise in the nonlocal scalar quantum field theory (QFT) with frac…

Strong-coupling expansions from field-space Fourier duality in scalar lattice field theory
Nikita A. Ignatyuk, Daniel Skliannyi
Dualities between quantum field theories provide useful descriptions of otherwise inaccessible parameter regimes. We develop a strong-coupling expansion for a class of Euclidean sc…
