Study reports observation of nonlinear disclination states

Higher-order topological insulators are unusual materials that can support topologically protected states. Recently discovered disclination states also belong to the class of higher-order topological states but are bound ...

Current takes a surprising path in quantum material

Cornell researchers have used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior ...
