Universal effective action for O(n)-symmetric λϕ^4 model from renormalization group
A. I. Sokolov, E. V. Orlov, V. A. Ul'kov +1
The RG expansions for renormalized coupling constants g_6 and g_8 of the 3D n-vector model are calculated in the 4-loop and 3-loop approximations respectively. Resummation of the R…

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…
