Description:
Author(s): P. M. R. Brydon, D. F. Agterberg, Henri Menke, and C. Timm The authors present a general theory for Fermi surfaces of Bogoliubov quasiparticles in superconductors with broken time-reversal symmetry. These Fermi surfaces form two-dimensional nodes of the superconducting gap, which are unique to pairing states with a “nonunitary” structure. This generates a nonsuperconducting magnetic order intertwined with superconductivity, which is responsible for inflating the expected zero- or one-dimensional nodes into Bogoliubov Fermi surfaces. Such Fermi surfaces should be present in a large class of superconductors that break time-reversal symmetry. [Phys. Rev. B 98, 224509] Published Fri Dec 14, 2018
