Holographic Fermi arcs and a d-wave gap
, 2010 We study fermion correlators in a holographic superfluid with a d-wave (spin two) order parameter. We find that, with a suitable bulk Majorana coupling, the Fermi surface is anisotropically gapped. At low temperatures the gap shrinks to four nodal points.

Quantum oscillations in Kondo Insulator SmB$_6$ [PDF]
, 2013 In Kondo insulator samarium hexaboride SmB$_6$, strong correlation and band hybridization lead to an insulating gap and a diverging resistance at low temperature. The resistance divergence ends at about 5 Kelvin, a behavior recently demonstrated to arise

Bulk Fermi surface of the Weyl type-II semimetallic candidate NbIrTe 4 [PDF]
, 2016 The electronic structure of WTe${}_{2}$ and of orthorhombic $\ensuremath{\gamma}$-MoTe${}_{2}$ are theoretically claimed to contain pairs of Weyl type-II points associated with linearly touching electron and hole pockets.

Butterfly magnetoresistance, quasi-2D Dirac Fermi surface and topological phase transition in ZrSiS [PDF]
Science Advances, 2016 An unusual angle-dependent topological phase transition and butterfly magnetoresistance were found in the Dirac semimetal ZrSiS. Magnetoresistance (MR), the change of a material’s electrical resistance in response to an applied magnetic field, is a ...

Anomalous Quasiparticle Reflection from the Surface of a $^3$He-$^4$He Dilute Solution
, 2017 A free surface of a dilute $^3$He-$^4$He liquid mixture is a unique system where two Fermi liquids with distinct dimensions coexist: a three-dimensional (3D) $^3$He Fermi liquid in bulk and a two-dimensional (2D) $^3$He Fermi liquid at the surface.

Comments on holographic Fermi surfaces [PDF]
Journal of High Energy Physics, 2009 Recently, a mechanism for the development of a fermi surface in a holographic model of large N QCD with a baryon chemical potential was proposed. We examine similar constructions to determine when this mechanism persists. We find a class of models in which it does.

Deformation of anisotropic Fermi surfaces due to electron-electron interactions
, 2006 We analyze the deformations of the Fermi surface induced by electron-electron interactions in anisotropic two dimensional systems. We use perturbation theory to treat, on the same footing, the regular and singular regions of the Fermi surface.
