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…
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_…
Néel transition, spin fluctuations, and pseudogap in underdoped cuprates by a Lorentz invariant four-fermion model in 2+1 dimensions
Manuel Reenders
We show that the Néel transition and spin fluctuations near the Néel transition in planar cuprates can be described by an SU(2) invariant relativistic four-fermion model in 2+1 dim…
Compositional and orientational ordering in rod-coil diblock copolymer melts
Manuel Reenders, Gerrit ten Brinke
The phase behavior of a melt of monodisperse rod-coil diblocks is studied. We derive a Landau free energy functional for both a compositional and a nematic order parameter. The exc…
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…
Nonperturbative infrared dynamics of three-dimensional QED with a four-fermion interaction
Valery Gusynin, Anthony Hams, Manuel Reenders
A non-linear Schwinger-Dyson (SD) equation for the gauge boson propagator of massless QED in one time and two spatial dimensions is studied. It is shown that the nonperturbative so…
