From: Efficient excitation-transfer across fully connected networks via local-energy optimization
Sketch of the physical situation investigated in this paper. We consider a fully connected network comprising N sites. The excitation is initially injected in one site of the network (darker green), while a different site is attached to a sink into which the excitation is transferred (at a rate \(\Gamma _{s}\)). The generic n-th site of the network is locally affected by dephasing noise (at a rate \(\gamma _{n}\)) and spontaneous emission, the latter causing the excitation to be irreversibly lost at rate \(\Gamma _{n}\). By optimizing the set of local energies \(h_{n}\), we systematically study the efficiency of excitation-transfer to the sink under different dephasing conditions
