摘要：
Exact diagonalizations indicate that the effective one-dimensional behavior (sliding Luttinger liquid phase) of the frustrated spin-1/2 crossed chain model, predicted by Starykh, Singh, and Levine [Phys. Rev. Lett. 88, 167203 (2002)], persists for a wide range of interchain couplings. The extension of the other phases (plaquette valence bond crystal and Neel long-range order) is made precise. The coexistence region of these two phases, proposed by Sachdev and Park [Ann. Phys. (N.Y.) 298, 58 (2002)], has at most a very narrow width.
