Surface States of Perovskite Iridates AIrO; Signatures of Topological Crystalline Metal with Nontrivial Index
Heung-Sik Kim, Yige Chen, Hae-Young Kee
There have been increasing efforts in realizing topological metallic phases with nontrivial surface states. It was suggested that orthorhombic perovskite iridates are classified as…

Topological Crystalline Metal in Orthorhombic Perovskite Iridates
Yige Chen, Yuan-Ming Lu, Hae-Young Kee
Since topological insulators were theoretically predicted and experimentally observed in semiconductors with strong spin-orbit coupling, more and more attention has been drawn to t…

Topological phases in Iridium oxide superlattices: quantized anomalous charge or valley Hall insulators
Yige Chen, Hae-Young Kee
We study topological phases in Iridium (Ir) oxide superlattices of orthorhombic perovskite-type grown along the [001] crystallographic axis. Due to strong spin-orbit coupling of Ir…
