Robust pinning of magnetic moments in pyrochlore iridates
W. C. Yang, W. K. Zhu, H. D. Zhou +6
Pyrochlore iridates A2Ir2O7 (A = rare earth elements, Y or Bi) hold great promise for realizing novel electronic and magnetic states owing to the interplay of spin-orbit coupling,…
Magnetic order and spin-orbit coupled Mott state in double perovskite (LaSr)CuIrO
W. K. Zhu, J. -C. Tung, W. Tong +11
Double-perovskite oxides that contain both 3d and 5d transition metal elements have attracted growing interest as they provide a model system to study the interplay of strong elect…
Manifestations of topological band crossings in bulk entanglement spectrum: An analytical study for integer quantum Hall states
Chi-Ken Lu, Dah-Wei Chiou, Feng-Li Lin
We consider integer quantum Hall states and calculate bulk entanglement spectrum by formulating the correlation matrix in guiding center representation. Our analytical approach is…
Conserved charges of order-parameter textures in Dirac systems
Igor F. Herbut, Chi-Ken Lu, Bitan Roy
A simple expression for the induced fermion current in the presence of a texture in mass-order-parameters in two-dimensional condensed-matter Dirac systems is derived using the rep…
Zero modes and charged Skyrmions in graphene bilayer
Chi-Ken Lu, Igor F. Herbut
We show that the electric charge of the Skyrmion in the vector order parameters that characterize the quantum anomalous spin Hall state and the layer-antiferromagnet in a graphene…
