Entanglement production in coupled chaotic systems : Case of the Kicked Tops
Jayendra N. Bandyopadhyay, Arul Lakshminarayan
Entanglement production in coupled chaotic systems is studied with the help of kicked tops. Deriving the correct classical map, we have used the reduced Husimi function, the Husimi…
Recurrence of fidelity in near integrable systems
R. Sankaranarayanan, Arul Lakshminarayan
Within the framework of simple perturbation theory, recurrence time of quantum fidelity is related to the period of the classical motion. This indicates the possibility of recurren…
Local Identities Involving Jacobi Elliptic Functions
Avinash Khare, Arul Lakshminarayan, Uday Sukhatme
We derive a number of local identities of arbitrary rank involving Jacobi elliptic functions and use them to obtain several new results. First, we present an alternative, simpler d…
What is random about a quantum random walk?
Arul Lakshminarayan
We use simple deterministic dynamical systems as coins in studying quantum walks. These dynamical systems can be chosen to display, in the classical limit, a range of behaviors fro…
