Out-of-time-order correlators of nonlocal block-spin and random observables in integrable and nonintegrable spin chains

Rohit Kumar Shukla, Arul Lakshminarayan, Sunil Kumar Mishra

Out-of-time-order correlators (OTOC) in the Ising Floquet system, that can be both integrable and nonintegrable is studied. Instead of localized spin observables, we study contiguo…
