Non-Markovian dynamics and quantum interference in open three-level quantum systems

The exact analytical solutions for the dynamics of the dissipative three-level V-type and Λ -type atomic systems in the vacuum Lorentzian environments are presented. Quantum interference between the spontaneous emissions of different decaying channels for the V-type atomic system is observed. For th...

Description
Summary:The exact analytical solutions for the dynamics of the dissipative three-level V-type and Λ -type atomic systems in the vacuum Lorentzian environments are presented. Quantum interference between the spontaneous emissions of different decaying channels for the V-type atomic system is observed. For the dissipative Λ -type atomic system, however, similar phenomenon of quantum interference does not exist. We demonstrate that quantum interference can be used to protect effectively the quantum entanglement and quantum coherence. The control of the transition from Markovian to non-Markovian processes is discussed.
