We compute the energy transport efficiency as a function of disorder and dephasing rates. We demonstrate that dephasing improves transport efficiency not only in the disordered case, but also in the ordered one. The maximal transport efficiency is obtained when the dephasing timescale matches the hopping timescale, which represent new examples of the Goldilocks principle at the quantum scale. Remarkably, we find that in weak dephasing regimes, away from optimal levels of environmental fluctuations, the <jats:italic>average<\/jats:italic> effect of increasing disorder is to improve the transport efficiency until an optimal value for disorder is reached. Our results suggest that rational design of the site energies statistical distributions could lead to better performances in transport systems at nanoscale when their natural environments are far from the optimal dephasing regime.<\/jats:p>","DOI":"10.1038\/srep18142","type":"journal-article","created":{"date-parts":[[2016,1,4]],"date-time":"2016-01-04T10:21:19Z","timestamp":1451902879000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Disorder-assisted quantum transport in suboptimal decoherence regimes"],"prefix":"10.1038","volume":"6","author":[{"given":"Leonardo","family":"Novo","sequence":"first","affiliation":[]},{"given":"Masoud","family":"Mohseni","sequence":"additional","affiliation":[]},{"given":"Yasser","family":"Omar","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2016,1,4]]},"reference":[{"key":"BFsrep18142_CR1","doi-asserted-by":"publisher","first-page":"782","DOI":"10.1038\/nature05678","volume":"446","author":"GS Engel","year":"2007","unstructured":"Engel, G.
