Using tensor network states to unravel the physics of quantum spin liquids inminimal, yet generic microscopic spin or electronic models remains notoriouslychallenging. A prominent open question concerns the nature of the insulatingground state of two-dimensional half-filled Hubbard-type models on thetriangular lattice in the vicinity of the Mott metal-insulator transition, aregime which can be approximated microscopically by a spin-1/2 Heisenberg modelsupplemented with additional "ring-exchange" interactions. Using a novel andefficient state preparation technique whereby we initialize full density matrixrenormalization group (DMRG) calculations with highly entangledGutzwiller-projected Fermi surface trial wave functions, we show -- contrary toprevious works -- that the simplest triangular lattice $J$-$K$ spin model withfour-site ring exchange likely does not harbor a fully gapless U(1) spinonFermi surface (spin Bose metal) phase on four- and six-leg wide ladders. Ourmethodology paves the way to fully resolve with DMRG other controversialproblems in the fields of frustrated quantum magnetism and strongly correlatedelectrons.
