        - 'T': Tensor networks oriented Krylov subspace method restricted to a
               tridiagonal effective matrix and using sequential operator
               application and orthonormalisation procedures. Implemented in
               tn_krylov.h
        - 'U': Tensor networks oriented Krylov subspace method calculating the
               full effective matrix and using sequential operator application
               and orthonormalisation procedures.
        - 'V': Tensor networks oriented Krylov subspace method restricted to a
               tridiagonal effective matrix and using concurrent variational
               operator application and orthonormalisation methods. Only
               implemented for MPS, has no sub-modes. May give wrong results if
               the initial state is very simple due to the variational
               application.

               MPS, has no sub-modes. May give wrong results if the initial
