Entangling and decohering influence of noisy perturbations. Stochastic anti-resonance in the time evolution of interacting qubits
Demetris P. K. Ghikas, Athanasios C. Tzemos
We study the entanglement evolution of two coupled qubits in interaction with an external environment and in the presence of an external magnetic field with a stochastic component.…

Quantum Entanglement dependence on bifurcations and scars in non autonomous systems. The case of Quantum Kicked Top
George Stamatiou, Demetris P. K. Ghikas
Properties related to entanglement in quantum systems, are known to be associated with distinct properties of the corresponding classical systems, as for example stability, integra…

A curvature dependent bound for entanglement change in classically chaotic systems
Demetris P. K. Ghikas, George Stamatiou
Using the Calogero-Moser model and the Nakamura equations for a multi-partite quantum system, we prove an inequality between the mean bi-partite entanglement rate of change under t…
