### wave function from MPS

Hello,

I would like to obtain the wave function coefficients from an MPS for a system where I conserve the U(1) symmetry. In principle, I would use:

Code: Select all

wf = psi.get_theta(0,L).to_ndarray().reshape(-1)[
where L is the length of the system, but I am not sure if this is correct.
Will the order of the coefficients change depending on the region of the phase diagram that I am studying?

Thank you

Joana
