Microscopic theory of magnetism in Sr3Ir2O7
Jean-Michel Carter, Hae-Young Kee
An intriguing idea of spin-orbit Mott insulator has been proposed to explain magnetic insulating behavior in various iridates. This scenario relies on the strength of the spin-orbi…
Theory of magnetism and metal-insulator transition in layered perovskite iridates
Jean-Michel Carter, V. Vijay Shankar, Hae-Young Kee
We investigate the metal-insulator transition in the layered Ruddelsden Popper series of strontium iridates Srn+1IrnO3n+1. Tight-binding models of t2g orbitals for n = 1, 2, and in…
Semimetal and Topological Insulator in Perovskite Iridates
Jean-Michel Carter, V. Vijay Shankar, M. Ahsan Zeb +1
The two-dimensional layered perovskite Sr2IrO4 was proposed to be a spin-orbit Mott insulator, where the effect of Hubbard interaction is amplified on a narrow J_{eff} = 1/2 band d…
Magnetic breakdown in ortho-II high-temperature cuprates
Jean-Michel Carter, Daniel Podolsky, Hae-Young Kee
The recent confirmation of closed Fermi surface in the high temperature cuprates via de Haas-van Alphen and Shubnikov-de haas oscillations calls for a theoretical investigation of…
