Impurity Bound States and Symmetry of the Superconducting Order Parameter in Sr2RuO4
Recent experiments on Sr2RuO4 have indicated the presence of linear nodes in the superconducting order parameter. Among the possible spin triplet states, 2D p-wave superconductivity with Eu symmetry appears to be inconsistent with the experiments, whereas the 2D f-wave order parameter with B1g × Eu symmetry turns out to be a more likely candidate. Here it is shown how the quasi-particle bound s...
متن کاملOptical conductivity of superconducting Sr2RuO4
– We compute the optical conductivity of 2D f-wave superconductors and also of the multigap model proposed recently by Zhitomirsky and Rice at T = 0K in the Born limit. The presence of interband impurity scattering was found to play an important role: the contributions from the two bands mix up, and new structures are seen in the tunneling density of states and in the optical spectrum as well, ...
متن کاملLine defects of a two-component vector order parameter.
The line density of line defects in terms of a two-component vector order parameter are obtained from the definition of topological charges of line defects. The spatial structure and bifurcation of line defects in three-dimensional space are also studied from the topological properties of the two-component vector order parameter. The branch conditions for generating, annihilating, colliding, sp...

متن کاملSupersolid phases of a doped valence-bond quantum antiferromagnet: evidence for a coexisting superconducting order parameter.
Motivated by numerical evidence of the valence-bond ground state of the two-dimensional Heisenberg pyrochlore lattice, we argue using a t-J model that it evolves under doping into novel phases characterized by superconductivity coexisting with the underlying valence-bond solid order. A fermionic mean-field theory supplemented by exact diagonalization results provide strong arguments in favor of...
