Electronic Structure of Pyrochlore Iridates: From Topological Dirac Metal to Mott Insulator
Xiangang Wan, Ari Turner, Ashvin Vishwanath +1
In 5d transition metal oxides such as the iridates, novel properties arise from the interplay of electron correlations and spin-orbit interactions. We investigate the electronic st…
Robust Dirac Point in Honeycomb Structure Nanoribbons with Zigzag Edges
Bo Xu, Jiang Yin, Hongming Weng +3
The zigzag edge graphene nanoribbon, which is an antiferromagnetic insulator, is found from the density-function theory calculation to display a robust Dirac point after N and B do…
The electronic structures and magnetic properties of perovskite ruthenates from constrained orbital hybridization calculations
Xiangang Wan, Jian Zhou, Jinming Dong
We introduce a method to analyze the effect of hybridization by shifting corresponding atomic levels using external potentials. Based on this approach, we study perovskite ruthenat…
Calculated Magnetic and Electronic Properties of Pyrochlore Iridates
Xiangang Wan, Jinming Dong, Sergey Y. Savrasov
Using density functional theory and LDA+U method, we investigate magnetic and electronic structure of YIrO and rare-earth based pyrochlore iridates. Our study rev…
Electronic Structure Calculations of Magnetic Exchange Interactions in Europium Monochalcogenides
Xiangang Wan, Jinming Dong, Sergej Y. Savrasov
Using a combination of local spin density and Hubbard 1 approximations we study the mechansim of exchange interacion in EuX (X=O, S, Se and Te). We reproduce known experimental res…
