[edit]The page states that the binder parameter at T~Tc is proportional to L to the power (1/nu) but does not say what nu is. — Preceding unsigned comment added by Wrww (talk • contribs) 22:21, 30 January 2014 (UTC)
Binder cumulant vs. kurtosis
[edit]The article states that the Binder cumulant is the kurtosis of the order parameter. Would that not be the "excess kurtosis" (-3 times)? Here is a source: https://mathworld.wolfram.com/KurtosisExcess.html . Balhe71 (talk) 13:43, 5 February 2025 (UTC)
Binder parameter for geometric phases
[edit]Also, a question: some quantities can not be expressed as operator expectation values. For example, the polarization of a crystalline system is a Berry-Zak phase. In this case, the Binder formalism has to be extended. Would it be of interest to mention this? Balhe71 (talk) 13:45, 5 February 2025 (UTC)
