Electromagnetically induced transparency in systems with degenerate autoionizing levels in Λ-configuration
T. Bui Dinh, W. Leoński, V. Cao Long +1
We discuss a Λ-like model of atomic levels involving two autoionizing (AI) states of the same energy. The system is irradiated by two external electromagnetic fields (strong -- dri…
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…
Sudden Death and Birth of Entanglement Effects for Kerr-Nonlinear Coupler
A. Kowalewska-Kudłaszyk, W. Leoński
We analyse the entanglement dynamics in a nonlinear Kerr-like coupler interacting with external environment. Whenever the reservoir is in a thermal vacuum state the entanglement (m…
Finite-dimensional states and entanglement generation for a nonlinear coupler
A. Kowalewska-Kudłaszyk, W. Leoński
We discuss a system comprising two nonlinear (Kerr-like) oscillators coupled mutually by a nonlinear interaction. The system is excited by an external coherent field that is resona…
