ArticleKruger, F.We study the S=1 square lattice Heisenberg antiferromagnet with spatially anisotropic nearest-neighbor couplings J1x and J1y frustrated by a next-nearest-neighbor coupling J2 numerically using the density-matrix renormalization-group DMRG method and a . . .
ArticleJiang, H.C.We numerically study the spin-1/2 antiferromagnetic Heisenberg model on the kagome lattice using the density-matrix renormalization group method. We find that the ground state is a magnetically disordered spin liquid, characterized by an exponential d . . .
ArticleWeng, M.Q.We numerically demonstrate that a supersolid phase exists in a frustrated hard-core boson system on a triangular lattice over a wide range of interaction strength. In the infinite repulsion Ising limit, we establish a mapping to the same problem with . . .
