Multifractal eigenstates of quantum chaos and the Thue-Morse sequence
N. Meenakshisundaram, Arul Lakshminarayan
We analyze certain eigenstates of the quantum baker's map and demonstrate, using the Walsh-Hadamard transform, the emergence of the ubiquitous Thue-Morse sequence, a simple sequenc…
Transport of Entanglement Through a Heisenberg-XY Spin Chain
V. Subrahmanyam, Arul Lakshminarayan
The entanglement dynamics of spin chains is investigated using Heisenberg-XY spin Hamiltonian dynamics. The various measures of two-qubit entanglement are calculated analytically i…
Multipartite Entanglement in a One-Dimensional Time Dependent Ising Model
Arul Lakshminarayan, V. Subrahmanyam
We study multipartite entanglement measures for a one-dimensional Ising chain that is capable of showing both integrable and nonintegrable behaviour. This model includes the kicked…
Cyclic Identities Involving Ratios of Jacobi Theta Functions
Avinash Khare, Arul Lakshminarayan, Uday Sukhatme
Identities involving cyclic sums of terms composed from Jacobi elliptic functions evaluated at equally shifted points were recently found. The purpose of this paper is to re-ex…
