3D quantum Hall effect of Fermi arcs in topological semimetals

, 2017
The quantum Hall effect is usually observed in 2D systems. We show that the Fermi arcs can give rise to a distinctive 3D quantum Hall effect in topological semimetals.

Parquet solution for a flat Fermi surface

, 1996
We study instabilities occurring in the electron system whose Fermi surface has flat regions on its opposite sides. Such a Fermi surface resembles Fermi surfaces of some high-$T_c$ superconductors.

Fermi surface interconnectivity and topology in Weyl fermion semimetals TaAs, TaP, NbAs, and NbP [PDF]

, 2015
The family of binary compounds including TaAs, TaP, NbAs, and NbP was recently discovered as the first realization of Weyl semimetals. In order to develop a comprehensive description of the charge carriers in these Weyl semimetals, we performed detailed ...

Marginal Fermi Liquid with a Two-Dimensional Patched Fermi Surface

, 1999
We consider a model composed of Landau quasiparticle states with patched Fermi surfaces (FS) sandwiched by states with flat FS to simulate the ``cold'' spot regions in cuprates. We calculate the one particle irreducible function and the self-energy up to

Unconventional Fermi surface in an insulating state [PDF]

Science, 2015
Probing the insulating state of SmB6 When a metal is subjected to a strong magnetic field, its electrons start rearranging into new energy levels, causing its electronic properties to oscillate as a function of the field.

Quantum oscillations and the Fermi surface topology of the Weyl semimetal NbP [PDF]

, 2015
The Weyl semimetal NbP was found to exhibit topological Fermi arcs and exotic magnetotransport properties. Here, we report on magnetic quantum-oscillation measurements on NbP and construct the three-dimensional Fermi surface with the help of band ...

Fermi Surface of the Most Dilute Superconductor

Physical Review X, 2013
The origin of superconductivity in bulk SrTiO_{3} is a mystery since the nonmonotonous variation of the critical transition with carrier concentration defies the expectations of the crudest version of the BCS theory. Here, employing the Nernst effect, an

Flow to strong coupling in the two-dimensional Hubbard model

, 2002
We extend the analysis of the renormalization group flow in the two-dimensional Hubbard model close to half-filling using the recently developed temperature flow formalism.
