Reaction center exciton states. The exciton states, $\widetilde{|\nu ⟩}$, are defined as eigenstates of the stationary state density matrix, namely, ${\rho }_e\widetilde{|\nu ⟩}=P_{\nu }\widetilde{|\nu ⟩}$; parameters were taken from Table 1, where parameter set 1 (a) assumes high dynamic disorder and parameter set 2 (b) assumes low dynamic disorder. Orange circles (radius scales with diagonal elements of $\widetilde{|\nu ⟩}\widetilde{⟨\nu |}$) indicate the participation of each pigment in an exciton state, and blue lines (thickness scales with absolute value of off-diagonal elements of $\widetilde{|\nu ⟩}\widetilde{⟨\nu |}$) indicate inter-pigment coherence. Listed are also the steady-state population P_ν and energy ε_ν of each exciton state. The numbering of the states is in energetically ascending order.
