The commensurate-disordered phase transition in 2D classical ATNNI model studied by DMRG

Abstract

The classical two-dimensional anisotropic triangular nearest-neighbor Ising (ATNNI) model is studied by the density matrix renormalization group (DMRG) technique when periodic boundary conditions are imposed. Applying the finite-size scaling to the DMRG results a commensurate-disordered (C-D) phase transition line as well as temperature and magnetic critical exponents are calculated. We conclude that the (C-D) phase transition in the ATNNI model belongs to the same universality class as the ordered-disordered phase transition of the Ising model.
