Topological surface states interacting with bulk excitations in the Kondo insulator SmB₆ revealed via planar tunneling spectroscopy

Samarium hexaboride (SmB₆), a well-known Kondo insulator in which the insulating bulk arises from strong electron correlations, has recently attracted great attention owing to increasing evidence for its topological nature, thereby harboring protected surface states. However, corroborative spectrosc...
