Topological phases in layered pyrochlore oxide thin films along the [111] direction

Xiang Hu, Andreas Rüegg, Gregory A. Fiete

We theoretically study a multi-band Hubbard model of pyrochlore oxides of the form A${}_2$B${}_2$O${}_7$, where B is a heavy transition metal ion with strong spin-orbit coupling, in a th…
