New Methods to Measure Phase Transition Strength

W Janke, D A Johnston and R Kenna


Abstract

A recently developed technique to determine the order and strength of phase transitions by extracting the density of partition function zeroes (a continuous function) from finite-size systems (a discrete data set) is generalized to systems for which ( i\/}) some or all of the zeroes occur in degenerate sets and/or ( ii\/}) they are not confined to a singular line in the complex plane. The technique is demonstrated by application to the case of free Wilson fermions.
