In a recent report on Science, M. Serlin and an interdisciplinary  research team in the Department of Physics, National Institute of Materials Science and the Kavli Institute for Theoretical Physics in the U.S. and Japan detailed the observation of a QAH effect in twisted bilayer graphene aligned to hexagonal boron nitride. They drove the effect via intrinsic strong interactions, which polarized the electrons into a single spin and valley resolved moir\u00e9 miniband (interference pattern).&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2020-01-intrinsic-quantized-anomalous-hall-effect.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Intrinsic quantized anomalous Hall effect in a moir\u00e9 heterostructure<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields).
