Spin correlations near the edge as probe of Dimer order in square-lattice Heisenberg models
T. Pardini, R. R. P. Singh
Recent numerical and analytical work has shown that for the square-lattice Heisenberg model the boundary can induce Dimer correlations near the edge which are absent in spin-wave t…

Spin-stiffness of anisotropic Heisenberg model on square lattice and possible mechanism for pinning of the electronic liquid crystal direction in YBCO
T. Pardini, R. R. P. Singh, A. Katanin +1
Using series expansions and spin-wave theory we calculate the spin-stiffness anisotropy in Heisenberg models on the square lattice with anisotropic couplings $J_x,J…

Magnetic order in coupled spin-half and spin-one Heisenberg chains in anisotropic triangular-lattice geometry
T. Pardini, R. R. P. Singh
We study spin-half and spin-one Heisenberg models in the limit where one dimensional (1-D) linear chains, with exchange constant J1, are weakly coupled in an anisotropic triangular…
