Anomalous dimensions of gauge-invariant amplitudes in massless effective gauge theories of strongly correlated systems
V. P. Gusynin, D. V. Khveshchenko, M. Reenders
We use the radial gauge to calculate the recently proposed ansatz for the physical electron propagator in such effective models of strongly correlated electron systems as the $QED_…
Magnetic field driven metal-insulator phase transition in planar systems
E. V. Gorbar, V. P. Gusynin, V. A. Miransky +1
A theory of the magnetic field driven (semi-)metal-insulator phase transition is developed for planar systems with a low density of carriers and a linear (i.e., relativistic like)…
On the normal phase of 2D Fermi liquid with weak attraction between particles
V. P. Gusynin, V. M. Loktev, I. A. Shovkovy
Proceeding from the simplest field theoretical model of 2D metal, the normal phase Green functions of the weakly interacting fermions and the order parameter fluctuations (responsi…
On the Superconductivity of 2D System with Arbitrary Carrier Density in External Magnetic Field
V. P. Gusynin, V. M. Loktev, I. A. Shovkovy
Selfconsistent equations which describe the order parameter and chemical potential behaviour in metalic system as functions of external magnetic field, , temperature, ,…
