Nodeless Hybridization as Proof of Trivial Topology in Samarium Hexaboride
E. D. L. Rienks, P. Hlawenka, J. Sánchez-Barriga +13
Calculations unanimously predict samarium hexaboride to be a topological Kondo insulator, the first topological insulator driven by strong electron correlation. As of today it appe…

A consistent view of the samarium hexaboride terminations to resolve the nature of its surface states
H. Herrmann, P. Hlawenka, K. Siemensmeyer +11
The research effort prompted by the prediction that SmB could be the first topological Kondo insulator has produced a wealth of new results, though not all of these seem compat…

Massless Dirac fermions in epitaxial graphene on Fe(110)
A. Varykhalov, J. Sánchez-Barriga, P. Hlawenka +1
Graphene grown on Fe(110)by chemical vapor deposition using propylene is investigated by means of angle-resolved photoemission. The presence of massless Dirac fermions is clearly e…
