EigensolverImaginaryTime
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.
