Classical chaotic signatures in Krylov space
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
In recent years, Krylov space approaches have emerged as a useful framework for characterizing dynamical chaos in a wide variety of physical systems. However, the connection betwee…
Quantum analogues of exponential sensitivity: from Loschmidt echo to Krylov complexity
Ignacio García-Mata, Diego A. Wisniacki
One of the fundamental manifestations of classical chaos is exponential sensitivity to initial conditions that is, two trajectories starting from nearly identical initial states di…
Quantum-to-classical correspondence in Krylov complexity
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
We study quantum-to-classical correspondence of the Krylov space for evolutions driven by unitary maps with a classical limit. This entails a proper definition of corresponding qua…
