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…
Running coupling constants of the Luttinger liquid
D. Boose, J. L. Jacquot, J. Polonyi
Two running coupling constants of the Luttinger liquid are computed in the fermion-fermion and fermion-antifermion channels. Nontrivial scaling laws are found together with Landau…
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…
Functional Callan-Symanzik Equation for the Coulomb Gas
Sebastiao Correia, Janos Polonyi, Jean Richert
A non-perturbative scheme, based on the functional generalization of the Callan-Symanzik equation is developed to treat the Coulomb interaction in an electron gas. The one-particle…
Effective action and density functional theory
J. Polonyi, K. Sailer
The effective action for the charge density and the photon field is proposed as a generalization of the density functional. A simple definition is given for the density functional,…
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…
