Universal critical coupling constants for the three-dimensional n-vector model from field theory
A. I. Sokolov, E. V. Orlov, V. A. Ul'kov +1
The field-theoretical renormalization group approach in three dimensions is used to estimate the universal critical values of renormalized coupling constants g_6 and g_8 for the O(…

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…
