Nearly flat band with Chern number C=2 on the dice lattice
Fa Wang, Ying Ran
We point out the possibility of nearly flat band with Chern number C=2 on the dice lattice in a simple nearest-neighbor tightbinding model. This lattice can be naturally formed by…
Possible interaction driven topological phases in (111) bilayers of LaNiO3
Kai-Yu Yang, Wenguang Zhu, Di Xiao +3
We use the variational mean-field approach to systematically study the phase diagram of a bilayer heterostructure of the correlated transition metal oxide LaNiO3, grown along the (…
Symmetry protected fractional Chern insulators and fractional topological insulators
Yuan-Ming Lu, Ying Ran
In this paper we construct fully symmetric wavefunctions for the spin-polarized fractional Chern insulators (FCI) and time-reversal-invariant fractional topological insulators (FTI…
Interface engineering of quantum Hall effects in digital transition metal oxide heterostructures
Di Xiao, Wenguang Zhu, Ying Ran +2
Topological insulators are characterized by a nontrivial band topology driven by the spin-orbit coupling. To fully explore the fundamental science and application of topological in…
Quantum Hall effects in a Weyl Semi-Metal: possible application in pyrochlore Iridates
Kai-Yu Yang, Yuan-Ming Lu, Ying Ran
There have been lots of interest in pyrochlore Iridates A2Ir2O7 where both strong spin-orbital coupling and strong correlation are present. A recent LDA calculation suggests that t…
Z2 spin liquid in S=1/2 Heisenberg model on Kagome lattice: A projective symmetry group study of Schwinger-fermion mean-field states
Yuan-Ming Lu, Ying Ran, Patrick A. Lee
With strong geometric frustration and quantum fluctuations, S=1/2 quantum Heisenberg antiferromagnets on the Kagome lattice has long been considered as an ideal platform to realize…
