The continuously intensifying demand for high-performance and miniaturized semiconductor
devices has pushed the aggressive downscaling of field-effect transistors (FETs) design …

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 …

Recent theoretical studies of topologically nontrivial electronic states in Kondo insulators
have pointed to the importance of spin-orbit coupling (SOC) for stabilizing these states …

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 …

The Kondo insulator SmB 6 has long been known to display anomalous transport behavior
at low temperatures, T< 5 K. In this temperatures range, a plateau is observed in the dc …

Recent theoretical models and experiments suggest that Sm B 6 is a topological Kondo
insulator. Here we report on heat capacity C (T) investigations of three single-crystalline Sm …

Kondo insulators are expected to transform into metals under a sufficiently strong magnetic
field. The closure of the insulating gap stems from the coupling of a magnetic field to the …

Resistivities of heavy-fermion insulators typically saturate below a characteristic temperature
T*. For some, metallic surface states, potentially from a non-trivial bulk topology, are a likely …
