Pseudogap and Fermi surface topology in the two-dimensional Hubbard model. [PDF]

, 2017
One of the distinctive features of hole-doped cuprate superconductors is the onset of a `pseudogap' below a temperature $T^*$. Recent experiments suggest that there may be a connection between the existence of the pseudogap and the topology of the Fermi ...

Effective mass and Fermi surface complexity factor from ab initio band structure calculations

npj Computational Materials, 2017
The effective mass is a convenient descriptor of the electronic band structure used to characterize the density of states and electron transport based on a free electron model.

Fermi Surface of Sr_{2}RuO_{4}: Spin-Orbit and Anisotropic Coulomb Interaction Effects. [PDF]

Physical Review Letters, 2016
The topology of the Fermi surface of Sr_{2}RuO_{4} is well described by local-density approximation calculations with spin-orbit interaction, but the relative size of its different sheets is not.

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.

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.

Orbital-dependent Fermi surface shrinking as a fingerprint of nematicity in FeSe [PDF]

, 2016
The large anisotropy in the electronic properties across a structural transition in several correlated systems has been identified as the key manifestation of electronic nematic order, breaking rotational symmetry.

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

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 ...

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.

ARPES Spectra of the Hubbard model

, 2001
We discuss spectra calculated for the 2D Hubbard model in the intermediate coupling regime with the dynamical cluster approximation, which is a non-perturbative approach.
