Magnetic Weyl and Dirac Kondo semimetal phases in heterostructures
Seulgi Ok, Markus Legner, Titus Neupert +1
We study a layered three-dimensional heterostructure in which two types of Kondo insulators are stacked alternatingly. One of them is the topological Kondo insulator SmB 6 , the ot…
Suppression of magnetic excitations near the surface of the topological Kondo insulator SmB6
P. K. Biswas, M. Legner, G. Balakrishnan +8
We present a detailed investigation of the temperature and depth dependence of the magnetic properties of 3D topological Kondo insulator SmB6 , in particular near its surface. We f…
Surface-state spin textures and mirror Chern numbers in topological Kondo insulators
Markus Legner, Andreas Rüegg, Manfred Sigrist
The recent discovery of topological Kondo insulators has triggered renewed interest in the well-known Kondo insulator samarium hexaboride, which is hypothesized to belong to this f…
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…
