Perturbation theory methods applied to critical phenomena
J. Kaupuzs
Different perturbation theory treatments of the Ginzburg-Landau phase transition model are discussed. This includes a criticism of the perturbative renormalization group (RG) appro…

Critical behavior of n-vector model with quenched randomness
J. Kaupuzs
We consider the Ginzburg-Landau phase transition model with O(n) symmetry (i.e., the n-vector model) which includes a quenched randomness, i.e., a random temperature disorder. We h…

Nonexistence of the non-Gaussian fixed point predicted by the RG field theory in 4-epsilon dimensions
J. Kaupuzs
The Ginzburg-Landau phase transition model is considered in d=4-epsilon dimensions within the renormalization group (RG) approach. The problem of existence of the non-Gaussian fixe…
