New Types of Off-Diagonal Long Range Order in Spin-Chains
J. C. Talstra, S. P. Strong, P. W. Anderson
We discuss new possibilities for Off-Diagonal Long Range Order (ODLRO) in spin chains involving operators which add or delete sites from the chain. For the Heisenberg and Inverse S…

Dynamical T=0 correlations of the S=1/2 1D Heisenberg Anti-Ferromagnet with 1/r^2 exchange in a magnetic field
J. C. Talstra, F. D. M. Haldane
We present a new selection rule for matrix elements of local spin operators in the ``Haldane-Shastry'' model. Based on this rule we extend a recent exact calculation \cite{…
