# Quantum entanglement dependence on bifurcations and scars in non-autonomous systems. The case of quantum kicked top

@article{Stamatiou2007QuantumED, title={Quantum entanglement dependence on bifurcations and scars in non-autonomous systems. The case of quantum kicked top}, author={George Stamatiou and Demetris P. K. Ghikas}, journal={Physics Letters A}, year={2007}, volume={368}, pages={206-214} }

Properties related to entanglement in quantum systems, are known to be associated with distinct properties of the corresponding classical systems, as for example stability, integrability and chaos. This means that the detailed topology, both local and global, of the classical phase space may reveal, or influence, the entangling power of the quantum system. As it has been shown in the literature, the bifurcation points, in autonomous dynamical systems, play a crucial role for the onset of… Expand
