Complete zero-energy flat bands of surface states in fully gapped chiral noncentrosymmetric superconductors
Clara J. Lapp, Julia M. Link, Carsten Timm
Noncentrosymmetric superconductors can support flat bands of zero-energy surface states in part of their surface Brillouin zone. This requires that they obey time-reversal symmetry…
p-wave superconductivity in Luttinger semimetals
Julia M. Link, Igor F. Herbut
We consider the three-dimensional spin-orbit-coupled Luttinger semimetal of "spin" particles in presence of weak attractive interaction in the (p-wave) channel, and det…
Time reversal symmetry breaking and -wave superconductivity of triple-point fermions
Subrata Mandal, Julia M. Link, Igor F. Herbut
We study the possibility of complex tensor (-wave) superconducting order in three-dimensional semimetals with chiral spin-1/2 triple-point fermions, which have an effective orbi…
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…
Out-of-bounds hydrodynamics in anisotropic Dirac fluids
Julia M. Link, Boris N. Narozhny, Egor I. Kiselev +1
We study the hydrodynamic behavior in two-dimensional, interacting electronic systems with merging Dirac points at charge neutrality. The dispersion along one crystallographic dire…
Universal collisionless transport of graphene
Julia M. Link, Peter P. Orth, Daniel E. Sheehy +1
The impact of the electron-electron Coulomb interaction on the optical conductivity of graphene has led to a controversy that calls into question the universality of collisionless…
Energetically constrained co-tunneling of cold atoms
Andrey R. Kolovsky, Julia Link, Sandro Wimberger
We study under-barrier tunneling for a pair of energetically bound bosonic atoms in an optical lattice with a barrier. We identify conditions under which this exotic molecule tunne…
