Operator growth in disordered spin chains: Indications for the absence of many-body localization

Physical Review Research
We consider the spreading of a local operator A in one-dimensional many-body systems with Hamiltonian H by calculating the k-fold commutator [H,[H,[...,[H,A]]]].

Operator-Valued Norms

, 2007
We introduce two kinds of operator-valued norms. One of them is an $L(H)$-valued norm. The other one is an $L(C(K))$-valued norm. We characterize the completeness with respect to a bounded $L(H)$-valued norm. Furthermore, for a given Banach space $\textbf{B}$, we provide an $L(C(K))$-valued norm on $\textbf{B}$.
