How do I use this algorithm? What does that parameter do?

imaginary time evolution with TDVP

Post by ipsun »

Hi,

I am trying to find the ground state of a system with long-range interactions and I want to try using TDVP with imaginary time evolution.

When I use TDVP for real time evolution everything works fine, but I am not sure whether it is implemented to also support imaginary time evolution?

Thank you! :)

That's currently not supported at the moment, as imaginary time evolution is generally much slower than variational methods like DMRG.
Why would you prefer TDVP over DMRG?
