“Several theory groups have speculated that analogues of these structures could emerge in quantized anomalous Hall systems, ...

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They’re a bit strange: their surfaces conduct electricity, yet their interiors do not, instead acting as ...

"A big motivating factor for studying magnetic topological insulators is the presence of the quantum anomalous Hall effect," says Illinois Physics graduate student and lead author Nina Bielinski.

The advantage of the new technique is that because it is based on the quantum anomalous Hall effect rather than the ordinary quantum Hall effect, it does not require the use of applied magnetic fields ...
