Abstract EN
A three-dimensional Ising-like system in a homogeneous external field is studied on the basis of the higher non-Gaussian measure density (the ρ6 model).
The presented solutions of recurrence relations for the coefficients of the effective measure densities and the generalized point of exit of the system from the critical regime are used for calculating the free energy of the system at temperatures T>Tc (Tc is the phase transition temperature in the absence of an external field).
A calculation technique is based on the first principles of statistical physics and is naturally realized without any general assumptions and without any adjustable parameters.
The obtained expression for the free energy does not involve series expansions in the scaling variable and is valid near the critical point not only in the regions of the so-called weak and strong external fields, but also in the crossover region between these fields, where power series in the scaling variable are not effective.
