DOI: 10.1007/s11128-016-1451-4
Abstract: Dynamics of an open two-qubit system is investigated in the post-Markovian regime, where the environments have a short-term memory. Each qubit is coupled to separate environment which is held in its own temperature. The inter-qubit… read more here.

DOI: 10.1088/1367-2630/aadcbd
Abstract: We provide a general discussion of the Liouvillian spectrum for a system coupled to a non-Markovian bath using Floquet theory. This approach is suitable when the system is described by a time-convolutionless master equation with… read more here.

DOI: 10.1088/1751-8121/aaea13
Abstract: We consider two qubits interacting with a common bosonic bath, but not directly between themselves. We derive the (bipartite) entanglement generation conditions for Gaussian non-Markovian dynamical maps and show that they are similar as in… read more here.

DOI: 10.1103/physrevlett.118.128301
Abstract: A general formalism is introduced to allow the steady state of non-Markovian processes on networks to be reduced to equivalent Markovian processes on the same substrates. The example of an epidemic spreading process is considered… read more here.

DOI: 10.1103/physrevlett.121.227401
Abstract: We calculate the exact many-body time dynamics of polaritonic states supported by an optical cavity filled with organic molecules. Optical, vibrational, and radiative processes are treated on an equal footing employing the time-dependent variational matrix… read more here.
