Discovery in a new class of materials called topological crystalline insulators.
An international team of scientists led by BC Physics Assoc. Prof. Vidya Madhavan and including Asst. Prof. Stephen Wilson have reported the discovery of coexisting massless and massive "Dirac Fermions" in a new class of materials called topological crystalline insulators. This work will be published in Science and was released in the Aug 29th edition of the advanced online publication 'Science Express' (http://www.sciencemag.org/content/early/2013/08/28/science.1239451.full). The findings are also described at http://www.eurekalert.org/pub_releases/2013-08/bc-ntc082913.php. Former post-doctoral associate Dr. Yoshinori Okada was the lead experimentalist in this work along with BC physics graduate students Daniel Walkup, Wenwen Zhou and Chetan Dhital.
