Thermodynamic characteristics of the 3D Ising system in $\rho ^6$ model approximation taking into account the confluent correction.\ І.\ High-temperature region

I.V. Pylyuk
M.P. Kozlovskii

Original method for the calculation of the free energy, entropy, internal energy, specific heat, susceptibility of the 3D Ising model is proposed. The calculation is performed for temperatures above the critical temperature in the approximation of the $\rho ^6$ model taking into account the first confluent correction. Contributions into thermodynamic characteristics of the system from short-wave and long-wave fluctuation modes of the spin moment density are considered separately. The dependence on microscopic parameters of the system has been extracted in expressions for the leading critical amplitudes and for the confluent correction amplitudes.
