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 …

Femtosecond nonlinear spectroscopy is the main tool for the time-resolved detection of
photophysical and photochemical processes. Since most systems of chemical interest are …

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

Noninterferometric experiments have been successfully employed to constrain models of
spontaneous wave function collapse, which predict a violation of the quantum superposition …

Non-Markovian master equations describe general open quantum systems when no
approximation is made. We provide the exact closed master equation for the class of …

General open quantum systems display memory features, their master equations are non-
Markovian. We show that the subclass of Gaussian non-Markovian open system dynamics is …

Caldeira and Leggett (CL), in a seminal paper, derived a master equation describing
Markovian quantum Brownian motion. Such an equation suffered from not being completely …

A new non-Markovian stochastic Schrödinger equation at finite temperatures is presented to
correctly describe charge carrier dynamics in organic molecular crystals. The electron …

We investigate the non-Markovian dynamics of quantum correlation between two initially
entangled nitrogen-vacancy centers (NVCs) embedded in photonic-crystal cavities (PCCs) …

Collapse models describe phenomenologically the quantum-to-classical transition by
adding suitable nonlinear and stochastic terms to the Schrödinger equation, thus (slightly) …
