cheapest methods are molecular mechanics approaches~\cite{MM}, while  more expensive and precise methods explicitly model the electronic  degrees of freedom by some level of approximated quantum mechanics,  such as density functional theory (DFT)\cite{Hohenberg_1964, Kohn_1965} (DFT)\cite{Hohenberg_1964,Kohn_1965}  or wave-function methods~\cite{Szabo}. We will focus on these last  approaches, since the computation time is dominated by the  calculation of the Hessian matrix, making it an ideal application for
