Infrared cutoff dependence of the critical flavor number in three-dimensional QED
V. P. Gusynin, M. Reenders
We solve, analytically and numerically, a gap equation in parity invariant QED_3 in the presence of an infrared cutoff μand derive an expression for the critical fermion number N_c…

Large N planar or bare vertex approximation and critical behavior of a SU(N) invariant four-fermion model in 2+1 dimensions
Manuel Reenders
A four-fermion model in 2+1 dimensions describing N Dirac fermions interacting via SU(N) invariant N^2-1 four-fermion interactions is solved in the leading order of the 1/N expansi…

Dynamical symmetry breaking in the gauged Nambu-Jona-Lasinio model
Manuel Reenders
The mechanism of dynamical chiral symmetry breaking is studied in the Abelian version of the gauged Nambu-Jona-Lasinio model in four dimensions. The most interesting feature of the…
