We consider a smooth interface between a topological nodal-line semimetal and a
topologically trivial insulator (eg, the vacuum) or another semimetal with a nodal ring of …

We have systematically studied the electromagnetic transport properties of PbTe thin films
under gate voltage modulation. The system demonstrates pronounced electron–electron …

Volkov-Pankratov surface bands arise in smooth topological interfaces, ie interfaces
between a topological and a trivial insulator, in addition to the chiral surface state imposed …

Volkov-Pankratov states are nontopological massive bound states which generally arise
across the smooth interface between two adjacent regions of a two-band semimetal, over …

Topological phases of matter have been attracting significant attention across diverse fields,
from inherently quantum systems to classical photonic and acoustic metamaterials. In …
