Abstract
A recent one-loop calculation has shown that, in the d-dimensional classical Heisenberg model at low temperatures, the absolute thermal fluctuations of the spin-stiffness constant are scale independent for dd=2. In addition, we find that the strength of the logarithmic correction for the relative fluctuations depends on the details of the boundary conditions.Keywords
