Open quantum systems (OQSs) cannot always be described with the Markov approximation,
which requires a large separation of system and environment time scales. An overview is …

We derive a hierarchy of stochastic evolution equations for pure states (quantum
trajectories) for open quantum system dynamics with non-Markovian structured …

The reduced dynamics of an open quantum system obtained from an underlying
microscopic Hamiltonian can in general only approximately be described by a time-local …

Stochastic methods are ubiquitous to a variety of fields, ranging from physics to economics
and mathematics. In many cases, in the investigation of natural processes, stochasticity …

We present a fully quantum dynamical treatment of a quantum heat engine and its baths
based on the Hierarchy of Pure States (HOPS), an exact and general method for open …

We show that the general and numerically exact Hierarchy of Pure States method (HOPS) is
very well applicable to calculate the reduced dynamics of an open quantum system. In …

Here we present a Lindblad master equation that approximates the Redfield equation, a well
known master equation derived from first principles, without significantly compromising the …

Energy transfer in the photosynthetic Fenna–Matthews–Olson (FMO) complex of green
sulfur bacteria is studied numerically taking all three subunits (monomers) of the FMO trimer …

A master equation derived from non-Markovian quantum state diffusion is used to calculate
the excitation energy transfer in the photosynthetic Fenna–Matthews–Olson pigment–protein …

We present a theory that efficiently describes the quantum dynamics of an electronic
excitation that is coupled to a continuous, highly structured phonon environment. Based on a …
