Universal sextic effective interaction at criticality
A. I. Sokolov, E. V. Orlov, V. A. Ul'kov
The renormalization group approach in three dimensions is used to estimate the universal critical value g_6^* of the dimensionless sextic effective coupling constant for the Ising…

On free energy of three-dimensional Ising model at criticality
A. I. Sokolov, V. A. Ul'kov, E. V. Orlov
Higher-order vertices at zero external momenta for the scalar field theory describing the critical behaviour of the Ising model are studied within the field-theoretical renormaliza…
