SUMMARY:Engineering magnetism and chiral edge state of quantum anomalous Ha
 ll\nsystem
CLASS:PUBLIC
DESCRIPTION:Summary \n\nKE HE\, TSINGHUA UNIVERSITY\n\nThe quantum anomalo
 us Hall (QAH) effect is a quantum Hall effect\ninduced by spontaneous magn
 etization instead of an external magnetic\nfield. The effect occurs in two
 -dimensional (2D) insulators with\ntopologically nontrivial electronic ban
 d structure which is\ncharacterized by a non-zero Chern number. The experi
 mental observation\nof the QAH effect in thin films of magnetically doped 
 (Bi\,Sb)2Te3\ntopological insulators (TIs) paves the way for practical app
 lications\nof dissipationless quantum Hall edge states.\n
