Nonperturbative renormalization group treatment of amplitude fluctuations for [phi]4 topological phase transitions

Show other versions (1)

The study of the Berezinskii-Kosterlitz-Thouless transition in two-dimensional |φ|4 models can be performed in several representations, and the amplitude-phase (AP) Madelung parametrization is a natural way to study the contribution of density fluctuations to nonuniversal quantities. We introduce a...
