dc.descriptionOver the past few years three dimensional Quantum Electrodynamics (QED$_3$) has attracted a lot of attention, because it may be an effective theory for the underdoped and non-superconducting region of the phase diagram of high $T_c$ cuprate compounds. We present results from lattice simulations of the non-compact version of the theory in order to address the issue of whether chiral symmetry is spontaneously broken when the number of fermion flavours $N_f$ is less than a critical value $N_{fc}$. Our results provide strong evidence that QED$_3$ is chirally symmetric for $N_f \geq 1.5$, implying that a pseudogap phase separates the superconducting phase from the antiferromagnetic phase.
