Bogoliubov Fermi Surfaces in Spin-1/2 Systems: Model Hamiltonians and Experimental Consequences
Chandan Setty, Yifu Cao, Andreas Kreisel +2
Bogoliubov Fermi surfaces (BFSs) are topologically protected regions of zero energy excitations in a superconductor whose dimension equals that of the underlying normal state Fermi…

Topological Ultranodal pair states in iron-based superconductors
Chandan Setty, Shinibali Bhattacharyya, Yifu Cao +2
Bogoliubov Fermi surfaces are contours of zero-energy excitations that are protected in the superconducting state. Here we show that multiband superconductors with dominant spin si…
