Measure for the Degree of Non-Markovian Behavior of Quantum Processes in Open Systems
read the original abstract
We construct a general measure for the degree of non-Markovian behavior in open quantum systems. This measure is based on the trace distance which quantifies the distinguishability of quantum states. It represents a functional of the dynamical map describing the time evolution of physical states, and can be interpreted in terms of the information flow between the open system and its environment. The measure takes on nonzero values whenever there is a flow of information from the environment back to the open system, which is the key feature of non-Markovian dynamics.

Stochastic unravelings for Heisenberg picture and trace-nonpreserving dynamics
The paper introduces a general framework extending piecewise-deterministic unravelings to arbitrary trace-nonpreserving master equations requiring only positivity and Hermiticity of the dynamics.

Two flavor neutrino oscillations in presence of non-Hermitian dynamics
A density matrix approach to non-Hermitian two-flavor neutrino oscillations shows steady-state probabilities not necessarily 1/2, indicating non-Markovian behavior.
