New Journal of Physics, 2015 A three-orbital itinerant-electron model involving d _xz , d _yz and d _xy Fe 3d orbitals is proposed for iron pnictides towards understanding the ( $\pi ,0$ ) ordered magnetism and magnetic excitations in these materials.

Do the surface Fermi arcs in Weyl semimetals survive disorder? [PDF]
, 2018 We theoretically study the topological robustness of the surface physics induced by Weyl Fermi-arc surface states in the presence of short-ranged quenched disorder and surface-bulk hybridization.

Frontiers in Physics, 2014 We have investigated orbital character and electron correlation effects on Fermi surfaces in the hole-overdoped iron pnictide superconductor KFe2As2, which shows a low Tc of ~4 K, by angle-resolved photoemission spectroscopy.

Spin-density wave Fermi surface reconstruction in underdoped YBa2Cu3O6+x [PDF]
, 2009 We consider the reconstruction expected for the Fermi surface of underdoped YBa2Cu3O6+x in the case of a collinear spin-density wave with a characteristic vector Q=(pi[1+/-2 delta],pi), assuming an incommensurability delta~0.06 similar to that found in ...

New Journal of Physics, 2020 Electronic systems with quasi-one-dimensional (Q1D) Fermi surface tend to form either a charge-density-wave (CDW) or a spin-density-wave ground state at low temperatures due to one-dimensional instabilities.

Spectral topology and its relation to Fermi arcs in strongly correlated systems
Physical Review Research, 2023 Fermi gases and liquids display an excitation spectrum that is simply connected, ensuring closed Fermi surfaces. In strongly correlated systems such as the cuprate superconductors, the existence of open sheets of Fermi surface known as Fermi arcs ...

Evidence for a small hole pocket in the Fermi surface of underdoped YBa2Cu3Oy
, 2015 The Fermi surface of a metal is the fundamental basis from which its properties can be understood. In underdoped cuprate superconductors, the Fermi surface undergoes a reconstruction that produces a small electron pocket, but whether there is another, as

Holographic Fermi surfaces in charge density wave from D2-D8
Journal of High Energy Physics, 2021 D2-D8 model admits a numerical solution that corresponds to a charge density wave and a spin density wave. Considering that as the background, we numerically solve the Dirac equation for probe fermions.

Weak magnetism and non-Fermi liquids near heavy-fermion critical points
, 2003 This paper is concerned with the weak-moment magnetism in heavy-fermion materials and its relation to the non-Fermi liquid physics observed near the transition to the Fermi liquid.
