Bogoliubov-Fermi surface with inversion symmetry and electron-electron interactions: relativistic analogies and lattice theory
Igor F. Herbut, Julia M. Link
We show that the general low-energy Bogoliubov-de Genness Hamiltonian in a multiband superconductor with broken time reversal and preserved inversion symmetry is a generator of rea…
Bogoliubov-Fermi Surfaces in Noncentrosymmetric Multicomponent Superconductors
Julia M. Link, Igor F. Herbut
We show that when the time reversal symmetry is broken in a multicomponent superconducting condensate without inversion symmetry the resulting Bogoliubov quasiparticles generically…
d-wave superconductivity and Bogoliubov-Fermi surfaces in Rarita-Schwinger-Weyl semimetals
Julia M. Link, Igor Boettcher, Igor F. Herbut
We uncover the properties of complex tensor (d-wave) superconducting order in three-dimensional Rarita-Schwinger-Weyl semimetals that host pseudospin-3/2 fermions at a fourfold lin…
Hydrodynamic transport in the Luttinger-Abrikosov-Beneslavskii non-Fermi liquid
Julia M. Link, Igor F. Herbut
We determine the shear viscosity and the dc electrical conductivity of interacting three-dimensional Luttinger semimetals, which have a quadratic band touching point in the energy…
Quantum critical scaling and holographic bound for transport coefficients near Lifshitz points
Gian Andrea Inkof, Joachim M. C. Kuppers, Julia M. Link +2
The transport behavior of strongly anisotropic systems is significantly richer compared to isotropic ones. The most dramatic spatial anisotropy at a critical point occurs at a Lifs…
Elastic response of the electron fluid in intrinsic graphene: The collisionless regime
Julia M. Link, Daniel E. Sheehy, Boris N. Narozhny +1
The elastic response of an electron fluid at finite frequencies is defined by the electron viscosity . We determine for graphene at the charge neutrality point in the…
