Classical bifurcations and entanglement in smooth Hamiltonian system
M. S. Santhanam, V. B. Sheorey, Arul Lakshminarayan
We study entanglement in two coupled quartic oscillators. It is shown that the entanglement, as measured by the von Neumann entropy, increases with the classical chaos parameter fo…
Entanglement measures in quantum and classical chaos
Arul Lakshminarayan, Jayendra N. Bandyopadhyay, M. S. Santhanam +1
Entanglement is a Hilbert-space based measure of nonseparability of states that leads to unique quantum possibilities such as teleportation. It has been at the center of intense ac…
Accelerator modes of square well system
R. Sankaranarayanan, V. B. Sheorey
We study accelerator modes of a particle, confined in an one-dimensional infinite square well potential, subjected to a time-periodic pulsed field. Dynamics of such a particle can…
Quantum Chaos of a particle in a square well : Competing Length Scales and Dynamical Localization
R. Sankaranarayanan, A. Lakshminarayan, V. B. Sheorey
The classical and quantum dynamics of a particle trapped in a one-dimensional infinite square well with a time periodic pulsed field is investigated. This is a two-parameter non-KA…
Chaos in a well : Effects of competing length scales
R. Sankaranarayanan, A. Lakshminarayan, V. B. Sheorey
A discontinuous generalization of the standard map, which arises naturally as the dynamics of a periodically kicked particle in a one dimensional infinite square well potential, is…
Chaos and Exponentially Localized Eigenstates in Smooth Hamiltonian Systems
M. S. Santhanam, V. B. Sheorey, A. Lakshminarayan
We present numerical evidence to show that the wavefunctions of smooth classically chaotic Hamiltonian systems scarred by certain simple periodic orbits are exponentially localized…
