Unsplit superconducting and time reversal symmetry breaking transitions in SrRuO under hydrostatic pressure and disorder
Vadim Grinenko, Debarchan Das, Ritu Gupta +7
There is considerable evidence that the superconducting state of SrRuO breaks time reversal symmetry. In the experiments showing time reversal symmetry breaking its onset t…

Impurity induced double transitions for accidentally degenerate unconventional pairing states
Bastian Zinkl, Manfred Sigrist
Non-magnetic impurities can lift the accidental degeneracy of unconventional pairing states, such as the -wave state recently proposed for SrRuO. This type of ef…

Superconducting gap anisotropy and topological singularities due to lattice translational symmetry and their thermodynamic signatures
Bastian Zinkl, Mark H. Fischer, Manfred Sigrist
Symmetry arguments based on the point group of a system and thermodynamic measurements are often combined to identify the order parameter in unconventional superconductors. However…
