Samarium hexaboride (SmB6) is an example of a Kondo insulator, in which strong electron
correlations cause a band gap to open. SmB6 hosts both a bulk insulating state and a …

Motivated by recent experiments on Kondo insulators, we theoretically study quantum
oscillations from disorder-induced in-gap states in small-gap insulators. By solving a non …

Samarium hexaboride is a classic three-dimensional mixed valence system with a high-
temperature metallic phase that evolves into a paramagnetic charge insulator below 40 K. A …

The report of a half-quantized thermal Hall effect and oscillatory structures in the
magnetothermal conductivity in the Kitaev material α-RuCl3 have sparked a strong debate …

Primarily considered a medium of geometric frustration, there has been a growing
recognition of the kagome network as a harbor of lattice-borne topological electronic …

The long search for insulating materials that possess low-energy quasiparticles carrying
electron's quantum numbers except charge—inspired by the neutral spin-1/2 excitations, the …

While boron forms a wide range of metal borides with important industrial applications, there
has been relatively little attention devoted to lanthanide boride clusters. Here we report a …

We develop a theory of quantum oscillations in insulators with an emergent Fermi sea of
neutral fermions minimally coupled to an emergent U (1) gauge field. As pointed out by …

Sm B 6 is a candidate topological Kondo insulator that displays surface conduction at low
temperatures. Here, we perform torque magnetization measurements as a means to detect …

Quantum oscillations in transport and thermodynamic parameters at high magnetic fields are
an unambiguous signature of the Fermi surface, the defining characteristic of a metal …
