The growth of operator entropy in operator growth
Abstract We study upper bounds on the growth of operator entropy S K in operator growth. Using uncertainty relation, we first prove a dispersion bound on the growth rate |∂ t S K | ≤ 2b 1∆S K , where b 1 is the first Lanczos coefficient and ∆S K is the variance of S K . However, for irreversible pro...
