Evidence for Time-Reversal-Symmetry-Broken Superconductivity in Locally Noncentrosymmetric SrPtAs
P. K. Biswas, H. Luetkens, T. Neupert +16
We report the magnetic and superconducting properties of locally noncentrosymmetric SrPtAs obtained by muon-spin-rotation/relaxation (muSR) measurements. Zero-field muSR reveals th…
Formation and consequences of heavy d-electron quasiparticles in Sr3Ru2O7
M. P. Allan, A. Tamai, E. Rozbicki +18
We report angle-resolved photoelectron spectroscopy measurements of the quantum critical metal Sr3Ru2O7 revealing itinerant Ru 4d-states confined over large parts of the Brillouin…
Signatures of unconventional pairing in near-vortex electronic structure of LiFeAs
Kyungmin Lee, Mark H. Fischer, Eun-Ah Kim
A major question in Fe-based superconductors remains the structure of the pairing, in particular whether it is of unconventional nature. The electronic structure near vortices can…
Possible pairing symmetries in SrPtAs with a local lack of inversion center
Jun Goryo, Mark H. Fischer, Manfred Sigrist
We discuss possible pairing symmetries in the hexagonal pnictide superconductor SrPtAs. The local lack of inversion symmetry of the two distinct conducting layers in the unit cell…
Spin-Orbit Coupling in LaAlO/SrTiO interfaces: Magnetism and Orbital Ordering
Mark H Fischer, Srinivas Raghu, Eun-Ah Kim
The combination of Rashba spin-orbit coupling and electron correlations can induce unusual phenomena in the metallic interface between SrTiO and LaAlO. We consider effects…
