Quantum correlations and entanglement in a model comprised of a short chain of nonlinear oscillators
J. K. Kalaga, A. Kowalewska-Kudłaszyk, W. Leoński +1
We discuss a model comprised of a chain of three Kerr-like nonlinear oscillators pumped by two modes of external coherent field. We show that the system can be treated as nonlinear…

Kullback-Leibler quantum divergence as an indicator of quantum chaos
A. Kowalewska-Kudłaszyk, J. K. Kalaga, W. Leoński +1
We discuss a system of a nonlinear Kerr-like oscillator externally pumped by ultra-short, external, coherent pulses. For such a system, we analyse the application of the Kullback-L…
