Nonideal statistical field theory at NLO
Abstract
In this work, we introduce a field theory capable of describing the critical properties of nonideal systems undergoing continuous phase transitions beyond the leading order radiative corrections or in the number of loops (effective field theories limited only to leading order were recently defined in the literature). These systems present defects, inhomogeneities and impurities as opposed to ideal ones which are perfect, homogeneous and pure. We compute the values of the critical exponents of the theory beyond leading order and compare with their corresponding experimental measured results. The results show some interplay between nonideal effects and fluctuations.
