Nodal Liquids and Duality
Nick E. Mavromatos, Sarben Sarkar
Using a SU(2)x U(1) gauge theory for a t-J model around a node of the Fermi surface, we discuss patterns of dynamical symmetry breaking, which may lead to a pseudogap phase and to…

Evidence for Deviations from Fermi-Liquid Behaviour in (2+1)-Dimensional Quantum Electrodynamics and the Normal Phase of High- Superconductors
I. J. R. Aitchison, N. E. Mavromatos
We provide evidence that the gauge-fermion interaction in multiflavour quantum electrodynamics in -dimensions is responsible for non-fermi liquid behaviour in the infrared…
