Krylov Complexity in Free and Interacting Scalar Field Theories with Bounded Power Spectrum

This talk will be based on  arXiv:2212.14702v2, in which we studied a notion of operator growth known as Krylov complexity in free and interacting quantum field theories. We will discuss in detail the effects of mass, perturbative interactions, and ultraviolet cutoffs on the Lanczos coefficients and Krylov complexity.
