Quantum walks with quantum chaotic coins: Of the Loschmidt echo, classical limit and thermalization
Sivaprasad Omanakuttan, Arul Lakshminarayan
Coined discrete-time quantum walks are studied using simple deterministic dynamical systems as coins whose classical limit can range from being integrable to chaotic. It is shown t…

Out-of-time-ordered correlators and quantum walks
Sivaprasad Omanakuttan, Arul Lakshminarayan
Out-of time-ordered correlators (OTOC) have recently attracted significant attention from the physics of many-body systems, to quantum black-holes, with an exponential growth of th…

Quantum walk on a toral phase space
Sivaprasad Omanakuttan, Arul Lakshminarayan
A quantum walk on a toral phase space involving translations in position and its conjugate momentum is studied in the simple context of a coined walker in discrete time. The result…
