Experimental consequences of Bogoliubov Fermi surfacesClara Johanna Lapp and •Carsten Timm — Institute of Theoretical Physics, Technische Universität Dresden

Superconductors involving electrons with orbital degrees of freedom can have internally anisotropic pairing states that are impossible in single-band superconductors. For example, in even-parity multiband superconductors that break time-reversal symmetry, nodes of the superconducting gap are generically inflated into two-dimensional Bogoliubov Fermi surfaces. The detection and characterization of these quasiparticle Fermi surfaces requires the understanding of their experimental consequences. We derive the low-energy density of states for various nodal structures. Based on this, we calculate the low-temperature forms of the electronic specific heat, the thermal conductivity, the magnetic penetration depth, and the NMR spin-lattice relaxation rate, in the clean limit.
