Electric field enhances ring exchange relative to Heisenberg interactions, shifting the CSL phase boundary to smaller t/U in the ring exchange model on the triangular lattice.
Take the output of the first step as the initial state for a run with the density matrix mixer on to escape local minima, with a maximum of 40 sweeps and bond dimension of b = 1600
