摘要：

We investigate phase transitions in three-dimensional scalar matrix models, with special emphasis on complex 2 x 2 matrices. The universal equation of state for weak first order phase transitions is computed, We also study the coarse grained free energy. Its dependence on the coarse graining scale gives a quantitative criterion for the validity of the standard treatment of bubble nucleation.
