Confinement as crossover
Janos Polonyi
The order parameter of confinement together with the haaron model of the QCD vacuum is reviewed and it is pointed out that confining forces are generated by the non-renormalizable,…
Modelling static impurities
Sebastiao Correia, Janos Polonyi, Jean Richert
A simple model is presented for the calculation of the quenched average over impurities which are rendered static by setting their mass equal to infinity. The path integral formali…
Functional Callan-Symanzik equation
Jean Alexandre, Janos Polonyi
We describe a functional method to obtain the exact evolution equation of the effective action with a parameter of the bare theory. When this parameter happens to be the bare mass…
An effective theory for conductance by symmetry breaking
Sebastiao Correia, Janos Polonyi, Jean Richert
An effective theory is suggested for the particle-anti particle and the particle-particle modes of strongly disordered electron systems. The effective theory is studied in the fram…
