Impurity-induced frustration: low-energy model of diluted oxides
Shiu Liu, A. L. Chernyshev
We provide a detailed derivation of the low-energy model for Zn-diluted La2CuO4 in the limit of low doping together with a study of the ground-state properties of that model. We co…

Impurity-induced frustration in correlated oxides
Cheng-Wei Liu, Shiu Liu, Ying-Jer Kao +2
Using the example of Zn-doped La2CuO4, we demonstrate that a spinless impurity doped into a non-frustrated antiferromagnet can induce substantial frustrating interactions among the…

Anisotropy-induced ordering in the quantum J1-J2 antiferromagnet
Tommaso Roscilde, Adrian Feiguin, Alexander L. Chernyshev +2
We study the effect of spin anisotropies on a frustrated quantum antiferromagnet using the J_1-J_2^{XXZ} model on the square lattice. The T=0 and finite-T phase diagrams of this mo…
