Topological invariants, surface states, and interaction-driven phase transitions in correlated Kondo insulators with cubic symmetry
Markus Legner, Andreas Rüegg, Manfred Sigrist
We construct a lattice model for a cubic Kondo insulator consisting of one spin-degenerate and orbital at each lattice site. The odd-parity hybridization between the two or…

Relating the entanglement spectrum of noninteracting band insulators to their quantum geometry and topology
Markus Legner, Titus Neupert
We study the entanglement spectrum of noninteracting band insulators, which can be computed from the two-point correlation function, when restricted to one part of the system. In p…
