Abstract:

 

The combination of strong electronic correlations and non-trivial topology presents a novel

paradigm with promising experimental realizations. In this talk I will discuss the case of SmB6, a

mixed-valent 4f material predicted to be a topological Kondo insulator. Recent quantum

oscillation, thermal transport, scanning tunneling microscopy, and electrical transport

measurements indicate that the bulk of flux-grown SmB6 is truly insulating whereas its surface

states host heavy masses and are sensitive to perturbations that break time reversal symmetry.
