Electronic structure, spin excitations, and orbital ordering in a three-orbital model for iron pnictides

open access: yesNew 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.

Zeeman-induced gapless superconductivity with a partial Fermi surface [PDF]

open access: yes, 2018
We show that an in-plane magnetic field can drive two-dimensional spin-orbit-coupled systems under superconducting proximity effect into a gapless phase where parts of the normal state Fermi surface are gapped, and the ungapped parts are reconstructed ...

Pressure-induced Anderson-Mott transition in elemental tellurium

open access: yesCommunications Materials, 2021
Elemental tellurium is a natural p-type semiconductor with a chiral structure and spin-polarized Fermi surface. Here, the authors show that the pressure-induced topological change of the Fermi surface at 17 kbar triggers an Anderson-Mott insulator-to ...

Fermi-Surface Reconstruction in the Periodic Anderson Model [PDF]

open access: yes, 2008
We study ground state properties of periodic Anderson model in a two-dimensional square lattice with variational Monte Carlo method. It is shown that there are two different types of quantum phase transition: a conventional antiferromagnetic transition ...

Fermi surface tomography [PDF]

open access: yes, 2021
Abstract Fermi surfaces, three-dimensional (3D) abstract interfaces that define the occupied energies of electrons in a solid, are important for characterizing and predicting the thermal, electrical, magnetic, and optical properties of crystalline metals and semiconductors [1].

Orbital character and electron correlation effects on two- and three-dimensional Fermi surfaces in KFe2As2 revealed by angle-resolved photoemission spectroscopy

open access: yesFrontiers 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.

Do the surface Fermi arcs in Weyl semimetals survive disorder? [PDF]

open access: yes, 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.

Discovery of an unconventional charge modulation on the surface of charge-density-wave material TaTe4

open access: yesNew 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.
