Addendum to ‘Finite-size scaling analysis of isotropic–polar phase transitions in an amphiphilic fluid’

Abstract

The isotropic–polar phase transition of a model amphiphilic fluid was studied by us by assuming that the model pertains to the universality class of a 3D Ising magnet (Melle et al 2012 J. Phys.: Condens. Matter 24 035103). In this addendum we reanalyze our model in a more sophisticated way by measuring directly the critical exponents in Monte Carlo simulations performed in the isothermal–isobaric ensemble. Using standard notation for the critical exponents we obtain β = 0.371, γ = 1.400, and ν = 0.714, in excellent agreement with literature data for the classical 3D Heisenberg fluid (Campostrini et al 2002 Phys. Rev. B 65 144520).
