We develop a perturbative technique for solving Markovian quantum dissipative dynamics,
with the perturbation parameter being a small gap in the eigenspectrum. As an example, we …

Light-induced processes that occur in nature, such as photosynthesis and
photoisomerization in the first steps in vision, are often studied in the laboratory using …

The development of spectroscopic techniques able to detect and verify quantum coherence
is a goal of increasing importance given the rapid progress of new quantum technologies …

The exact factorization of the electron–nuclear wavefunction is applied to the study of photo-
isomerization of a retinal chromophore model. We describe such an ultrafast nonadiabatic …

Open quantum systems with nearly degenerate energy levels have been shown to exhibit
long-lived metastable states in the approach to equilibrium, even when modelled with …

Many important open quantum systems, such as light harvesting systems irradiated with
natural incoherent light, present challenging computational problems. Specifically, such …
