tebd on 2d lattice/ MPS with dangling legs
Posted: 31 May 2020, 12:03
Hi!
I am considering the problems of how to apply tebd on 2d lattices.
My thought was to cut the 1d segments of 2d lattices and apply tebd on it.
On implementing this idea, I have one problem.
On constructing MPS states from these 1d segments, we have dangling legs across MPS states, vUP and vDOWN.
The current MPS setting does not have this functionality.
One option would be to use GroupedSite. We can group up leg, down leg, and physical leg.
However, constructing operators for tebd is a bit cumbersome (although not impossible).
I am just wondering whether Tenpy has the functionality for these dangling legs.
Best.
