-junction to probe antiphase s-wave pairing in iron pnictide superconductors
Wei-Qiang Chen, Fengjie Ma, Zhong-Yi Lu +1
Josephson junctions between a -based superconductor with antiphase s-wave pairing and a conventional s-wave superconductor are studied. The translational invariance in a plan…
Theory for Superconductivity in Iron Pnictides at Large Coulomb U Limit
Wei-Qiang Chen, Kai-Yu Yang, Yi Zhou +1
Superconductivity in iron pnictides is studied by using a two-orbital Hubbard model in the large U limit. The Coulomb repulsion induces an orbital-dependent pairing between charge…
Symmetry of superconducting states with two orbitals on a tetragonal lattice: application to
Yi Zhou, Weiqiang Chen, Fu-chun Zhang
We use group theory to classify the superconducting states of systems with two orbitals on a tetragonal lattice. The orbital part of the superconducting gap function can be either…
Quantum Oscillations in Magnetic Field Induced Antiferromagnetic Phase of Underdoped Cuprates : Application to Ortho-II YBa2Cu3O6.5
Wei-Qiang Chen, Kai-Yu Yang, T. M. Rice +1
Magnetic field induced antiferromagnetic phase of the underdoped cuprates is studied within the t-t'-J model. A magnetic field suppresses the pairing amplitude, which in turn may i…
