FLOW article published in Phys. Rev. Lett.
For the first time we have found the optimal route to turbulence, and the localized disturbance to a laminar flow that takes that route. We have used optimal control theory to optimize the route to the statistically steady turbulent state characterized by the largest entropy production.
