Recurrence network analysis in a model tripartite quantum system
Abstract
In a novel approach to quantum dynamics, we apply the tools of the recurrence network analysis to the dynamics of the quantummechanical expectation values of observables. We construct and analyse ɛrecurrence networks from the timeseries data of the mean photon number in a model tripartite quantum system governed by a nonlinear Hamiltonian. The role played by the intensitydependent fieldatom coupling in the dynamics is investigated. Interesting features emerge as a function of a parameter characterising this intensitydependent coupling in both the shorttime and the longtime dynamics. In particular, we examine the manner in which standard measures of the network theory such as the average path length, the link density and the clustering coefficient, depend on this parameter.
