Deviations from Fermi-Liquid behaviour in (2+1)-dimensional Quantum Electrodynamics and the normal phase of high-$T_c$ Superconductors

I. J. R. Aitchison, N. E. Mavromatos

We argue that the gauge-fermion interaction in multiflavour quantum electrodynamics in $(2+1)$-dimensions is responsible for non-fermi liquid behaviour in the infrared, in the se…
