TL;DR Summary
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?
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
