EigensolverImaginaryTime

Section SCF::Eigensolver
Type float
Default 0.1

The imaginary-time step that is used in the imaginary-time evolution method (Eigensolver = evolution) to obtain the lowest eigenvalues/eigenvectors. It must satisfy EigensolverImaginaryTime > 0. Increasing this value can make the propagation faster, but could lead to unstable propagations.
