Author(s): Zhu, Z; White, SR | Abstract: © 2015 American Physical Society. We study the S=1/2 Heisenberg model on the triangular lattice with nearest- and next-nearest-neighbor interactions J1 and J2 with the density matrix renormalization group, on long open cylinders with widths up to nine lattice spacings. In an intermediate J2 region 0.06â‰J2/J1â‰0.17, we find evidence for a spin liquid (SL) state with short range spin-spin, bond-bond, and chiral correlation lengths, bordered by a classical 120° Neel ordered state at small J2 and by a two sublattice collinear magnetically ordered state at larger J2. Focusing on J2/J1=0.1, we find a number of signatures of a gapped SL phase.
