The Anti-Ferromagnetic Vacuum
Janos Polonyi
Certain effective vertices may generate a non-homogeneous, periodic vacuum structure. The excitations above such a vacuum are studied in the framework of the and gauge models…
Renormalization Group Analysis of the Heavy Field Decoupling in a Scalar Theory
A. Bonanno, J. Polonyi, D. Zappalá
The problem of two coupled scalar fields, one with mass much lighter than the other is analysed by means of Wilson's renormalization group approach. Coupled equations for the poten…
Mini-Instantons in SU(2) Gauge Theory
Vincenzo Branchina, Janos Polonyi
The effects of instantons close to the cut-off is studied in four dimensional SU(2) gauge theory with higher order derivative terms in the action. It is found in the framework of t…
Anti-Ferromagnetic Condensate in Yang-Mills Theory
Jochen Fingberg, Janos Polonyi
SU(2) gauge theory with competing interactions is shown to possess a rich phase structure with anti-ferromagnetic vacua. It is argued that the phase boundaries persist in the weak…
