I have a simple question. Let’s say I make a 2D hamiltonian for DMRG using triangular_lattice function and get a ground state after running the code. How can I know what index of the returned MPS corresponds to which x and y coordinates of the 2D system? In essence, I’m asking how is the ordering o…

It’s a good question, thanks for asking. First of all, the coordinates x1,x2,y1,y2 are unfortunately not implemented for trianguar_lattice which was just an oversight or missing thing we need to add. So we should add that in the future. But really the important thing anyway isn’t the spatial layout…

Hi, Miles!

Is there a way to define custom lattices as easily ? Say, I want to define some triangular lattice bound to the square lattice. like the one on a screen , for example?

Best,
Ian.
