Quench dynamics of collective modes in fractional quantum Hall bilayers
Zhao Liu, Ajit C. Balram, Zlatko Papić +1
We introduce different types of quenches to probe the non-equilibrium dynamics and multiple collective modes of bilayer fractional quantum Hall states. We show that applying an ele…
Designing Xenes with Two-Dimensional Triangular Lattice
Xu Duan, Zhao Liu, Brendan M. Hanrahan +2
Xenes, graphene-like two-dimensional (2D) monoelemental crystals with a honeycomb symmetry, have been the focus of numerous experimental and theoretical studies. In comparison, sin…
Doping dependence of electronic structure of infinite-layer NdNiO2
Zhao Liu, Chenchao Xu, Chao Cao +3
We investigate the electronic structure of nickelate superconductor NdNiO2 upon hole doping, by means of density-functional theory and dynamical mean-field theory. We demonstrate t…
Engineering Quantum Hall Phases in Synthetic Bilayer Graphene System
Ze-Pei Cian, Tobias Grass, Abolhassan Vaezi +2
Synthetic quantum Hall bilayer (SQHB), realized by optically driven monolayer graphene in the quantum Hall regime, provides a flexible platform for engineering quantum Hall phases…
Gate-Tunable Fractional Chern Insulators in Twisted Double Bilayer Graphene
Zhao Liu, Ahmed Abouelkomsan, Emil J. Bergholtz
We predict twisted double bilayer graphene to be a versatile platform for the realization of fractional Chern insulators readily targeted by tuning the gate potential and the twist…
Microscopic Diagnosis of Universal Geometric Responses in Fractional Quantum Hall Liquids
Liangdong Hu, Zhao Liu, D. N. Sheng +2
Topological quantum liquids contain internal degrees of freedom that are coupled to geometric response. Yet, an explicit and microscopic identification of geometric response remain…
