If 'M' means the total uniform magnetization (i.e. M = \sum s_i^z), the uniform susceptibility and <M2>-<M>2 differ by the factor \beta/N (\beta = 1/T and N the number of sites). If 'M' is the magnetization per site (\sum s_i^z / N), then the factor becomes \beta \times N.

hello, I try to understand all examples in alps-applications. How can I figure out what exactly is in the output as "uniform susceptibility" (say in Ising) and why it is not simply <M2>-<M>2? In which part of the code it is hidden? Tadeusz
