DMRG simulations indicate that two-leg t-J ladders can enter a Luttinger liquid regime with gapless spin and charge modes exhibiting spin-charge separation signatures under tuned plaquette hopping, exchange, and doping.
DMRG calculations on three-leg t-J ladders show power-law decaying pair correlations upon hole doping into the 1/3-filled spin-gapped state, with exponentially decaying spin correlations.
