Take the tour ×  I have a system with a number of measurables
(in time). Some measurables are discrete some are continuous
(within the measurement accuracy). How can I determine whether
my system experiences criticality or not?  I am looking for many
different ways to (dis)proof criticality.  See here for critical
phenomena http://en.wikipedia.org/wiki/Critical_phenomena.
share|improve this question Can you tell us a little more about
your research? Linking to single wikipedia pages is a bit on the
light side. Also, do you have some specific qualm about
criticality that leads you to believe it is fundamentally
flawed, in spite of decades of reasonable application? This
would make for a better question and discussion than "I [want
to] (dis)prove criticality". –  Jen Aug 2 '11 at 15:48 There are
various ways of seeing that system might be critical (absence of
scale, singularities with certain behavior in correlators or
macroscopic quantities, etc.). In general it's very hard to
determine whether system is crit
