Nature has mastered the art of molecular self-assembly, evolving from a very limited number of building blocks an impressive diversity of photosynthetic light-harvesting complexes, which are highly versatile and efficient. Understanding the sensitive interplay between the self-assembled superstructures and their functional properties is highly desirable for the synthesis of new materials, the design and operation of organic-based devices. I will first focus on energy transfer and spectroscopy of photosynthetic light-harvesting complexes, and give a systematic link that relates structure with fonction.

I will then present the dynamics of light-harvesting complexes in the context of the interpretation of the experimental 2D electronic spectra, discuss the influence of excitation conditions, and propose a scheme for the quantum simulation of many-body decoherence. The dynamics of quantum systems will then be presented in a unitary fermi gas, with the implementation of friction free strokes that can be used in the design of quantum heat engines for finite time thermodynamics.
