The namesake parameter of one model of this phenomenon has a critical value of root 2 over 2, above which the transition to it is second-order. A deviation from this behavior is an effect named for Kondo. The aforementioned model of this behavior, derived by extremizing an order parameter, is due to Ginzberg and Landau. A better-known model for this behavior predicts bosonic bound states between conduction electrons; these are the Cooper pairs of the BCS theory. FTP, name this physical phenomenon first observed by Heike
