During the last couple of years, due to tremendous progresses on the experimental side, there has been an intensified debate on the possible role of quantum mechanics in the context of biophysics - i.e. in systems which are rightfully characterized as widely open, disordered, noisy, “complex”. Inspired by some analogies between paradigmes of biological and technological light-energy...

It is well known that the efficiency of photovoltaic cells can benefit from upconversion of sub-bandgap light. Upconversion by triplet-triplet-annihilation is a very promising mechanism for this application. It employs two molecular species, one of which emits higher energy photons via fluorescence upon triplet-triplet-annihilation, whereas the second species sensitizes this process by...

An overview will be given of our current understanding of quantum complexity and the quantum-classical boundary in biological and material systems. In particular, we will discuss (i) whether "quantum-driven" functionality in these high-dimensional, structured systems is a robust feature or rather an accidental occurrence, (ii) to what extent quantum entanglement "scales up" into these systems...

Quantum dynamics is ubiquitous in chemistry; it underlies photochemistry, electron transfer processes, nonradiative transitions, spectroscopy and much more. However, elucidating the quantum dynamics of complex systems remains a central challenge.
The problem has two aspects to it. One is the cost of solution of the time dependent Schrödinger equation which typically grows exponentially with...
