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.
DMRG calculations on the two-leg Lieb ladder Hubbard model identify a ferrimagnetic insulator at half filling and a narrow superconducting Luther-Emery phase near filling 2/3.
