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 …

Strongly correlated electron systems at the border of magnetism are of active current
interest, particularly because the accompanying quantum criticality provides a route towards …

Topological invariants of electron wavefunctions in condensed matter reveal many intriguing
phenomena,. A notable example is provided by topological insulators, which are …

In metals, orbital motions of conduction electrons on the Fermi surface are quantized in
magnetic fields, which is manifested by quantum oscillations in electrical resistivity. This …

The relation between mechanical and electrical relaxation in polymer/lithium-salt complexes
is a fascinating and still unresolved problem in condensed-matter physics, yet has an …

Recent quantum oscillation experiments on SmB 6 pose a paradox, for while the angular
dependence of the oscillation frequencies suggest a 3D bulk Fermi surface, SmB 6 remains …

The interplay between strong electron interactions and band topology is a new frontier in the
search for exotic quantum phases. The Kondo insulator SmB6 has emerged as a promising …

Kondo insulator materials—such as CeRhAs, CeRhSb, YbB12, Ce3Bi4Pt3 and SmB6—are
3 d, 4 f and 5 f intermetallic compounds that have attracted considerable interest in recent …

Topological insulators give rise to exquisite electronic properties because of their spin-
momentum locked Dirac-cone-like band structure. Recently, it has been suggested that the …

We have investigated the low-temperature conducting state of two Kondo insulators, SmB 6
and Ce 3 Bi 4 Pt 3, which have been theoretically predicted to host topological surface …
