Symmetry, nodal structure, and Bogoliubov Fermi surfaces for nonlocal pairing

  title={Symmetry, nodal structure, and Bogoliubov Fermi surfaces for nonlocal pairing},
  author={Carsten Timm and Ankita Bhattacharya},
  journal={Physical Review B},
Multiband effects can lead to fundamentally different electronic behavior of solids, as exemplified by the possible emergence of Fermi surfaces of Bogoliubov quasiparticles in centrosymmetric superconductors which break time-reversal symmetry. We extend the analysis of possible pairing symmetries, the corresponding nodal structure, and the Bogoliubov Fermi surfaces in two directions: We include nonlocal pairing and we consider internal degrees of freedom other than the effective angular…

Bogoliubov Fermi surfaces from pairing of emergent $j=3/2$ fermions on the pyrochlore lattice

We examine the appearance of superconductivity in the strong-coupling limit of the Hubbard model on the pyrochlore lattice. We focus upon the limit of half filling, where the normal-state band

Classification of time-reversal symmetric topological superconducting phases for conventional pairing symmetries

Based on a recently developed framework, we conduct classifications of time-reversal symmetric topological superconductors with conventional pairing symmetries. Our real-space approach clarifies the

Experimental consequences of Bogoliubov Fermi surfaces

Superconductors involving electrons with internal degrees of freedom beyond spin can have internally anisotropic pairing states that are impossible in single-band superconductors. As a case in point,

Distortional weak-coupling instability of Bogoliubov Fermi surfaces

Centrosymmetric multiband superconductors which break time-reversal symmetry generically have two-dimensional nodes, i.e., Fermi surfaces of Bogoliubov quasiparticles. We show that the coupling of

Bogoliubov Fermi Surfaces in Superconductors with Broken Time-Reversal Symmetry.

It is shown that, for an even-parity nodal superconducting state which spontaneously breaks time-reversal symmetry, the low-energy excitation spectrum generally does not belong to any of these categories and has extended Bogoliubov Fermi surfaces, which are topologically protected from being gapped by a Z_{2} invariant.

Instability of j=32 Bogoliubov Fermi surfaces

Exotic quantum phases including topological states and non-Fermi liquids may be realized by quantum states with total angular momentum $j=3/2$, as manifested in HgTe and pyrochlore iridates.

Superconductivity in three-dimensional spin-orbit coupled semimetals

Motivated by the experimental detection of superconductivity in the low-carrier density half-Heusler compound YPtBi, we study the pairing instabilities of three-dimensional strongly spin-orbit

Bogoliubov Fermi surfaces: General theory, magnetic order, and topology

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

Pairing of j=3/2 Fermions in Half-Heusler Superconductors.

It is shown that pairing occurs between j=3/2 fermion states, which leads to qualitative differences from the conventional theory of pairing, which permits Cooper pairs with quintet or septet total angular momentum, in addition to the usual singlet and triplet states.

Inflated nodes and surface states in superconducting half-Heusler compounds

The half-Heusler superconductors such as YPtBi are multiorbital systems with both strong spin-orbit coupling and broken inversion symmetry. The spin-orbit coupling allows for the formation of Cooper

Bogoliubov-Fermi Surfaces in Noncentrosymmetric Multicomponent Superconductors.

We show that when the time reversal symmetry is broken in a multicomponent superconducting condensate without inversion symmetry the resulting Bogoliubov quasiparticles generically exhibit

Superconductivity in spin- 3/2 systems: Symmetry classification, odd-frequency pairs, and Bogoliubov Fermi surfaces

The possible symmetries of the superconducting pair amplitude is a consequence of the fermionic nature of the Cooper pairs. For spin-1/2 systems this leads to the SPOT = −1 classification of
