Nucleation-type criticality with infinite number of free-energy minima beyond mean-field theory

We study the phase diagram of a three-dimensional Heisenberg model with Dzyaloshinski--Moriya interaction under the presence of Potts-like anisotropy. The phase transition between the winding phase and the ferromagnetically ordered phase exhibits a critical phase transition with anomalous features such as critical expo...
