Quarter-filled Kane-Mele Hubbard model: Dirac half metals
نویسندگان
چکیده
Recent experimental success in the realization of two-dimensional (2D) magnetism has stimulated search for new magnetic 2D materials with strong anisotropy and high Curie temperature. One promising subgroup systems are Dirac half-metals (DHM) which have gained a lot interest recently, as they host high-temperature quantum anomalous Hall effect (QAHE). This article discusses predictions intrinsic DHMs identifies them realizations Kane-Mele Hubbard model at quarter filling. proposed unification contributes to firmer understanding these suggests pathways discovery DHM systems.

Rashba spin orbit coupling in the Kane-Mele-Hubbard model
Spin-orbit (SO) coupling is the crucial parameter to drive topological insulating phases in electronic band models. In particular, the generic emergence of SO coupling involves the Rashba term which fully breaks the SU(2) spin symmetry. As soon as interactions are taken into account, however, many theoretical studies have to content themselves with the analysis of a simplified U(1) conserving S...
متن کاملKane-Mele-Hubbard model on the π-flux honeycomb lattice
We consider the Kane-Mele-Hubbard model with a magnetic π flux threading each honeycomb plaquette. The resulting model has remarkably rich physical properties. In each spin sector, the noninteracting band structure is characterized by a total Chern number C = ±2. Fine-tuning of the intrinsic spin-orbit coupling λ leads to a quadratic band crossing point associated with a topological phase trans...

متن کاملThe topological Anderson insulator phase in the Kane-Mele model
It has been proposed that adding disorder to a topologically trivial mercury telluride/cadmium telluride (HgTe/CdTe) quantum well can induce a transition to a topologically nontrivial state. The resulting state was termed topological Anderson insulator and was found in computer simulations of the Bernevig-Hughes-Zhang model. Here, we show that the topological Anderson insulator is a more univer...
متن کاملMetallicity in the half-filled Holstein-Hubbard model
We re-examine the Peierls insulator to Mott insulator transition scenario in the one-dimensional Holstein-Hubbard model where, at half-filling, electron-phonon and electron-electron interactions compete for establishing chargeand spin-density-wave states, respectively. By means of large-scale density-matrix renormalization group calculations we determine the spin, single-particle and two-partic...
