The Time Evolving Density Matrix with Orthogonal Polynomial Algorithm (TEDOPA) is a numerically exact technique to simulate open quantum systems interacting with arbitrarily structured environments. The algorithm has been developed in order to analyse excitonically coupled systems in structures of biological relevance at physiological temperatures, though there is a wide range of applications in solid state physics as well.
These technical developments are illustrated, based upon its successful application to reproduce the experimental observation of long-lived coherences in the Fenna-Matthews-Olson complex. Further applications regarding similar harvesting pigment protein structures are also considered.
