• Abstract: Quantum non-Markovianity modifies the environmental decoherence of a system. This situation is enriched in complex systems owing to interactions among subsystems. We consider the problem of distinguishing the multiple sources of non-Markovianity using a simple power spectrum technique, applied to a qubit interacting with another qubit via a Jaynes-Cummings type Hamiltonian and simultaneously subjected to some well known noise channels, such as, the random telegraph noise and non-Markovian amplitude damping, which exhibit both Markovian as well as non-Markovian dynamics under different parameter ranges.

  We study the dynamics of a qubit system in contact with a thermal bath made up of few ancillas, in which system-ancilla and ancilla-ancilla interactions are considered. Results clearly indicate that the information backflows decrease when new ancillas are added to the bath, which sheds light on the nature of the Markovian to non-Markovian transition.

  Non-Markovian memory effects can be characterized in an exact analytical way. Dissipative-entanglement-generation in this kind of dynamics can only emerge when a time-reversal symmetry is broken. It is also found that departures from Markovianity can equivalently be represented through a statistical mixture of Markovian dephasing dynamics.

  We investigate the coherence and non-Markovianity of a quantum tunneling system whose barrier is fluctuated by a telegraph noise. It is found that there is no strong relation between the coherence of the system and non-Markovianity dynamics except in a region in which these two tend to change their behavior at the intermediate noise color for two initial states.
