Orbital-selective Dirac fermions and extremely flat bands in frustrated kagome-lattice metal CoSn

Journal Article Liu, Zhonghao ; Li, Man ; Wang, Qi ; ... - Nature Communications

Layered kagome-lattice 3d transition metals are emerging as an exciting platform to explore the frustrated lattice geometry and quantum topology. However, the typical kagome electronic bands, characterized by sets of the Dirac-like band capped by a phase-destructive flat band, have not been clearly observed, and their orbital physics are even less well investigated. Here, we present close-to-textbook kagome bands with orbital differentiation physics in CoSn, which can be well described by a minimal tight-binding model with single-orbital hopping in Co kagome lattice. The capping flat bands with bandwidth less than 0.2 eV run through the whole Brillouin zone, especially themore »« less

Emergent orbitals in the cluster Mott insulator on a breathing kagome lattice

Journal Article Chen, Gang ; Lee, Patrick A. - Physical Review. B

Motivated by the recent developments on cluster Mott insulating materials such as the cluster magnet LiZn₂Mo₃O₈, we consider the strong plaquette charge ordered regime of the extended Hubbard model on a breathing kagome lattice and reveal the properties of the cluster Mottness. The plaquette charge order arises from the intersite charge interaction and the collective motion of three localized electrons on the hexagon plaquettes. This model leads naturally to a reduction of the local moments by 2/3, as observed in LiZn₂Mo₃O₈. Furthermore, at low temperatures, each hexagon plaquette contains an extra orbital-like degree of freedom in addition to the remainingmore »« less

Spin-orbital liquids and insulator-metal transitions on the pyrochlore lattice

Journal Article Swain, Nyayabanta ; Karmakar, Madhuparna ; Majumdar, Pinaki - Physical Review. B

The two orbital Hubbard model, with the electrons additionally coupled to a complex magnetic background, arises in the pyrochlore molybdates. The background involves local moments Hund's coupled to the electrons, driving double exchange ferromagnetism, and antiferromagnetic (AF) tendency arising from competing superexchange. The key scales include the Hubbard repulsion and the superexchange, both of which can be tuned in these materials. They control the phase transition from a ferromagnetic metal to a spin glass metal and then to a spin glass (Mott) insulator. We provide a comprehensive description of the ground state of this model using an unrestricted Hartree-Fock schememore »« less

Effect of disorder on the electrical properties of amorphous conducting carbon films: Observance of field induced metal--insulator transition?

Journal Article Meenakshi, V ; Subramanyam, S V - International Journal of Modern Physics B

In this work, the influence of disorder on the electrical properties (DC conductivity and Magnetoresistance) of amorphous conducting carbon films, prepared by the pyrolysis of Tetra chloro phthalic anhydride, is reported and discussed. The low temperature electrical properties are analyzed in terms of the various models developed for disordered electronic systems. The results indicate the possibility of a metal--insulator (M-I) transition, both as a function of preparation temperature and an external magnetic field.
