Pair-breaking in superconductors with strong spin-orbit coupling
D. C. Cavanagh, Daniel F. Agterberg, P. M. R. Brydon
We study the influence of symmetry-breaking perturbations on superconductivity in multiorbital materials, with a particular focus on an external magnetic field. We introduce the fi…
Field-angle dependence reveals odd-parity superconductivity in CeRhAs
J. F. Landaeta, P. Khanenko, D. C. Cavanagh +8
CeRhAs is an unconventional superconductor with multiple superconducting phases and K. When , it shows a field-induced transition at $μ_…
Non-symmorphic symmetry and field-driven odd-parity pairing in CeRhAs
D. C. Cavanagh, T. Shishidou, M. Weinert +2
Recently, evidence has emerged for a field-induced even- to odd-parity superconducting phase transition in CeRhAs [S. Khim et al., Science 373 1012 (2021)]. Here we argue t…
General theory of robustness against disorder in multi-band superconductors
D. C. Cavanagh, P. M. R. Brydon
We investigate the influence of general forms of disorder on the robustness of superconductivity in multiband materials. Specifically, we consider a general two-band system where t…
Fate of the Hebel-Slichter peak in superconductors with strong antiferromagnetic fluctuations
D. C. Cavanagh, B. J. Powell
We show that magnetic fluctuations can destroy the Hebel-Slichter peak in conventional superconductors. The Hebel-Slichter peak has previously been expected to survive even in the…
Robustness of unconventional -wave superconducting states against disorder
D. C. Cavanagh, P. M. R. Brydon
We investigate the robustness against disorder of superconductivity in multiband systems where the fermions have four internal degrees of freedom. This permits unconventional -w…
Microwave Conductivity Distinguishes Between Different d-wave States: Umklapp Scattering in Unconventional Superconductors
D. C. Cavanagh, B. J. Powell
Microwave conductivity experiments can directly measure the quasiparticle scattering rate in the superconducting state. We show that this, combined with knowledge of the Fermi surf…
Nuclear Magnetic Resonance in Low-Symmetry Superconductors
D. C. Cavanagh, B. J. Powell
We consider the nuclear spin-lattice relaxation rate, in superconductors with accidental nodes. We show that a Hebel-Slichter-like peak occurs even in the absence of an is…
