The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

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 …

An open quantum system refers to a system that is further coupled to a bath system
consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is …

To write an introduction to the dynamics of open quantum systems may seem at first a
complicated, albeit perhaps unnecessary, task. On the one hand, the field is quite broad and …

Studies of the dynamics of open quantum systems are limited by the large Hilbert space of
typical environments, which is too large to be treated exactly. In some cases, approximate …

Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Electron–phonon coupling is important in many physical phenomena, eg photosynthesis,
catalysis and quantum information processing, but its impacts are difficult to grasp on the …

Photosynthesis is the natural process that converts solar photons into energy-rich products
that are needed to drive the biochemistry of life. Two ultrafast processes form the basis of …

Over the past few decades, coherent broadband spectroscopy has been widely used to
improve our understanding of ultrafast processes (eg, photoinduced electron transfer, proton …

Understanding the rules of life is one of the most important scientific endeavours and has
revolutionised both biology and biotechnology. Remarkable advances in observation …
