Doping the Kane-Mele-Hubbard model: A Slave-Boson Approach
Jun Wen, Mehdi Kargarian, Abolhassan Vaezi +1
We study the Kane-Mele-Hubbard model both at half-filling and away from half-filling using a slave-boson mean-field approach at zero temperature. We obtain a phase diagram at half-…
Topological Insulators and Quantum Spin Liquids
Gregory A. Fiete, Victor Chua, Mehdi Kargarian +4
In this paper we review some connections recently discovered between topological insulators and certain classes of quantum spin liquids, focusing on two and three spatial dimension…
Competing Exotic Topological Insulator Phases in Transition Metal Oxides on the Pyrochlore Lattice with Distortion
Mehdi Kargarian, Jun Wen, Gregory A. Fiete
In this work we investigate the phase diagram of heavy (4d and 5d) transition metal oxides on the pyrochlore lattice, such as those of the form , where A is a r…
Interaction-driven topological insulators on the kagome and the decorated honeycomb lattices
Jun Wen, Andreas Rüegg, C. -C. Joseph Wang +1
We study the spinless and spinful extended Hubbard models with repulsive interactions on the kagome and the decorated honeycomb ("star") lattice. Using Hartree-Fock mean-field theo…
Topological Insulators on the Decorated Honeycomb Lattice
Andreas Rüegg, Jun Wen, Gregory A. Fiete
We show that the decorated honeycomb lattice supports a number of topological insulating phases with a non-trivial Z_2 invariant and time-reversal symmetry protected gapless edge m…
