Internal space renormalization group for the Luttinger model
Janos Polonyi, Franck Stauffer
The absence of fermionic, asymptotical one-particle states in the Luttinger model raises the suspicion that the interactions are actually strong at the vicinity of the Fermi points…
Internal Space Renormalization Group Methods for Atomic and Condensed Matter Physics
Janos Polonyi
The functional renormalization group method is used to take into account the vacuum polarization around localized bound states generated by external potential. The application to A…
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…
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…
The deconfinement phase transition as an Aharonov-Bohm effect
Janos Polonyi
A subjective and incomplete list of interesting and unique features of the deconfinement phase transition is presented. Furthermore a formal similarity of the density matrix of the…
