The vicinity of hyper-honeycomb β-Li2IrO3 to a three-dimensional Kitaev spin liquid state.
TL;DR: The promise of the very recently synthesized hyper-honeycomb iridate β-Li2IrO3 is established, which reveals the presence of large ferromagnetic first-neighbor Kitaev interactions, while a second-NEighbor antiferromagnetic Heisenberg exchange drives the ground state from ferro to zigzag order via a three-dimensional Kitaeva spin liquid and an incommensurate phase.
Journal ArticleDOI
Absence of surface states for LiFeAs investigated using density functional calculations
Alexander Lankau,Klaus Koepernik,Sergey Borisenko,V. B. Zabolotnyy,Bernd Büchner,Jeroen van den Brink,Helmut Eschrig +6 more
TL;DR: In this article, the authors investigated the cleaving behavior of LiFeAs and determined its surface electronic structure by detailed density functional calculations, and showed that due to the neutral surface of LiFEAs after cleaving, barely any influence of the surface on the electronic states is present.
Journal ArticleDOI
Ordered states in the Kitaev-Heisenberg model: From 1D chains to 2D honeycomb
TL;DR: In this article, the ground state of the 1D Kitaev-Heisenberg (KH) model using the density-matrix renormalization group and Lanczos exact diagonalization methods was obtained.
Journal ArticleDOI
Theoretical Prediction of a Time-Reversal Broken Chiral Superconducting Phase Driven by Electronic Correlations in a Single TiSe 2 Layer
TL;DR: It is found that electronic correlations can give rise to charge-density-wave order and two kinds of superconductivity, one of which is particularly exciting as it is chiral, breaking time-reversal symmetry.
Journal ArticleDOI
Entangled tetrahedron ground state and excitations of the magnetoelectric skyrmion material Cu2OSeO3
TL;DR: In this paper, the authors used a microscopic multiboson theory for its magnetic ground state and excitations, and established the presence of two distinct types of modes: a low-energy manifold that includes a gapless Goldstone mode and a set of weakly dispersive high-energy magnons.
