Abstract:
Isotropic XY is considered. It describes interaction of quantum spins on 1-dimesional lattice. Alternatevly one can call the model XXO Hiesenberg antiferromagnet. We solved long standing problem of evaluation of temperature corelations. We proved that correlation function of the model is τ\tau function of Ablowitz-Ladik PDE. We explicitly evaluated asymptotics.
