Evidence for 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 provide evidence that the gauge-fermion interaction in multiflavour quantum electrodynamics in $(2+1)$-dimensions is responsible for non-fermi liquid behaviour in the infrared…
