Several kinds of coherence have recently been shown to affect the performance of light-
harvesting systems, in some cases significantly improving their efficiency. Here, we classify …

Microtubules are biological protein polymers with critical and diverse functions. Their
structures share some similarities with photosynthetic antenna complexes, particularly in the …

Nanotubular molecular self-aggregates are characterized by a high degree of symmetry and
they are fundamental systems for light-harvesting and energy transport. While coherent …

Efficient devices for light harvesting and photon sensing are fundamental building blocks of
basic energy science and many essential technologies. Recent efforts have turned to …

We report the results of an in-depth study of the role of graph topology on quantum transport
efficiency in random removal and Watts–Strogatz networks. By using four different …

Photosynthesis is the basic process used by plants to convert light energy in reaction
centers into chemical energy. The high efficiency of this process is not yet understood today …

A tight-binding model is introduced for describing the dynamics of an exciton on an
extended star graph whose central node is occupied by a trap. On this graph, the exciton …

We study the quantum dynamics of a photoexcitation uniformly distributed at the periphery of
an extended star network (with NB branches of length LB). More specifically, we address …

In this paper, the theory of the transfer efficiency of a light-harvesting system consisting of a
trimer ring coupled to an acceptor site is presented. When the ring has a prepared excitation …

Using a tight binding model, we investigate the dynamics of an exciton on a disordered
extended star graph whose central site acts as an energy trap. When compared with what …
