A The exciton dynamics in the FMO complex

Click For Summary
The discussion focuses on studying coherence transfer of excitation in the FMO complex using the Lindblad master equation. There are challenges in applying the Lindblad equation due to the complexity of the system, which contains seven bacteriochlorophylls (Bchls). The possibility of treating each chlorophyll as a two-level system is questioned, along with exploring alternative methods for describing exciton dynamics. References to quantum effects in quantum biology are mentioned as part of the research context. The conversation emphasizes the need for effective modeling techniques in this area of study.

TL;DR
can we treat the exciton in the FMO complex as a two level system to apply the Lindblad equation?
I want to study the coherence transfer of the excitation in the FMO complex, so I have to solve the Lindblad master equation. Can I treat my system as a two level system?

Can you give a specific reference? It would help to know what source you are working from.
 
in fact, I work with many reference, like Quantum effects in quantum biology
indeed I find some difficulties to apply the Lindblad equation on the FMO complex(it's protein contain 7 Bchls) so I wonder if I can treat each chlorophyll as a two system level ? or there's other way to describe the exciton dynamics in the FMO complex?
 
For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
