Objective

This application translates the theoretical framework from the Müh et al. (2014) paper into an interactive experience. The primary goal is to quantitatively model the optical properties (like light absorption) of the CP29 pigment-protein complex. To do this, we build a "virtual model" based on the fundamental principles of quantum mechanics and the physical structure of the complex.

The Frenkel Exciton Model

The entire simulation is built upon the Frenkel Exciton Model. This is a powerful theoretical tool with a key assumption: the individual chlorophyll molecules (pigments) are distinct entities, but they are close enough to "feel" each other's presence through electromagnetic interactions. When light is absorbed, the excitation isn't necessarily confined to a single pigment. Instead, it can become a collective property shared across multiple pigments. This shared, delocalized excitation is what we call an exciton.
