Description:
Author(s): Lu Zhao, Jianfeng Wang, Junwei Liu, Yong Xu, Bing-Lin Gu, Qi-Kun Xue, and Wenhui Duan Inspired by helicity dependent optical phenomena in chiral metamaterials the authors exploit the idea of helicity degree of freedom of Dirac fermions. They perform a first-principles study of SnTe films and show that giant helicity splitting in the band structures can be induced under moderate electric field. They suggest using helicity as an extra degree of freedom for helicity-resolved filtering and focusing of Dirac fermions. [Phys. Rev. B 92, 041408(R)] Published Tue Jul 21, 2015
