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 …

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 …

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 …

The inverted resistance method was used in this study to extend the bulk resistivity of S m B
6 to a regime where the surface conduction overwhelms the bulk. Remarkably, regardless of …

We investigated the crystal-electric field ground state of the 4 f manifold in the strongly
correlated topological insulator SmB 6 using core-level nonresonant inelastic x-ray …

Resonant x-ray emission spectroscopy was used to determine the pressure dependence of
the f-electron occupancy in the Kondo insulator SmB 6. Applied pressure reduces the f …

The Kondo insulator samarium hexaboride (SmB 6) has been intensely studied in recent
years as a potential candidate of a strongly correlated topological insulator. One of the most …

We have carried out bulk-sensitive hard x-ray photoelectron spectroscopy measurements on
in situ cleaved and ex situ polished SmB 6 single crystals. Using the multiplet structure in the …

The proximity effect at the interface between a topological insulator and a superconductor is
predicted to give rise to chiral topological superconductivity and Majorana fermion …

We show that novel low temperature properties of bulk SmB 6, including the sudden growth
of the de Haas–van Alphen (dHvA) amplitude (and heat capacity) at millikelvin temperatures …
