Introduction,g the density matrix are introduced, with reference to which we compare the performance of indicators obtained directly from optical and qubit tomograms. Second, we demonstrate the usefulness of applying time series and network analysis (originating from classical dynamical systems theory) to the dy

Entanglement at Avoided Level Crossings, systems in which, with the variation of an appropriate parameter, some of the energy levels move close to each other and then move apart, avoiding level crossing. We summarize known results pointing out that standard quantum entanglement measures extremize at avoided energy-level crossings. Hence s

,Dynamics and Entanglement Indicators in Bipartite CV Systems,hic approach is successful in mirroring entanglement trends. Even though off-diagonal correlations in the density matrix are not explicitly seen in tomograms, the tomographic approach provides a viable alternative to standard entanglement assessors that involve state reconstruction.

Dynamics of the Mean Photon Number: Time Series and Network Analysis,e-grained phase space, network quantifiers, etc. provide insights into the effects of a finite versus infinite number of atomic levels, intensity-dependent couplings, and bipartite versus tripartite systems. This study also provides readily recognizable departures in the quantum case from known resu
