Phys. Rev. B 67, 060503(R) (2003) [4 pages]Coexistence of bulk antiferromagnetic order and superconductivity in the QED3 theory of copper oxides
Within the framework of the QED3 theory of cuprate superconductivity it is argued that bulk antiferromagnetic (AF) order can coexist with d-wave superconductivity in the underdoped region, in agreement with recent experiments. The AF order arises from the phase fluctuating d-wave superconductor via the mechanism of spontaneous chiral-symmetry breaking, provided that fluctuations are sufficiently strong. The phase diagram for this coexistence is mapped out by means of analytical and numerical solutions of the underlying Dyson-Schwinger equation in the large N limit. © 2003 The American Physical Society URL:
