Spin-density Wave in Ising-coupled Antiferromagnetic Chains

J. P. Rodriguez, P. D. Sacramento, V. R. Vieira

The effect of anisotropy in the nearest-neighbor spin interactions that couple consecutive spin-1/2 antiferromagnetic chains is studied theoretically by considering the l…

Gapless spectrum in a class of S=1 exchange models with long-range interactions

P. D. Sacramento, V. R. Vieira

We present evidence for the absence of a gap in a class of S=1 antiferromagnetic exchange models. The spin exchange is long-ranged of the type where .…
