Short time behavior of continuous time quantum walks on graphs
Balázs Endre Szigeti, Gábor Homa, Zoltán Zimborás +1
Dynamical evolution of systems with sparse Hamiltonians can always be recognized as continuous time quantum walks (CTQWs) on graphs. In this paper, we analyze the short time asympt…

Generalized quantum Zeno dynamics and ergodic means
Norbert Barankai, Zoltán Zimborás
We prove the existence of uniform limits for certain sequences of products of contractions and elements of a family of uniformly continuous propagators acting on a Hilbert or a Ban…
