Composite fermions in the fractional quantum spin Hall effect
Hongquan Liu, D. E. Feldman
Well-understood fractional quantum Hall states in GaAs and graphene can be described in terms of weakly interacting composite fermions. It is natural to expect that the same unifyi…
Nearly perfect Fermi surface nesting in hole-doped LaNiO enables bulk superconductivity without pressure or strain
Chengliang Xia, Jiale Chen, Hongquan Liu +1
The discovery of high-temperature superconductivity in Ruddlesden-Popper nickelates has drawn great attention. However, unlike cuprates and iron-based superconductors, Ruddlesden-P…
Probing bilayer topological order with layer-resolved transport
Hongquan Liu, J. I. A. Li, D. E. Feldman
Shot noise has been used to measure fractional charges of anyons. The value of the charge imposes constraints on fractional statistics but does not determine it. This issue is part…
Electronic Structure of Superconducting Infinite-Layer Lanthanum Nickelates
Wenjie Sun, Zhicheng Jiang, Chengliang Xia +12
Revealing the momentum-resolved electronic structure of infinite-layer nickelates is essential for understanding this new class of unconventional superconductors, but has been hind…
Sensitive dependence of pairing symmetry on Ni- crystal field splitting in the nickelate superconductor LaNiO
Chengliang Xia, Hongquan Liu, Shengjie Zhou +1
The discovery of high-temperature superconductivity in LaNiO under pressure has drawn great attention. However, consensus has not been reached on its pairing symmetry i…
Emergent topological states via digital (001) oxide superlattices
Zhiwei Liu, Hongquan Liu, Jiaji Ma +3
Oxide heterostructures exhibit many intriguing properties. Here we provide design principles for inducing multiple topological states in (001) (O)/(O) oxid…
An electronic origin of charge order in infinite-layer nickelates
Hanghui Chen, Yi-feng Yang, Guang-Ming Zhang +1
A charge order (CO) with a wavevector is observed in infinite-layer nickelates. Here we use first-principles calculations to demonstr…
Manipulating Berry curvature of SrRuO3 thin films via epitaxial strain
Di Tian, Zhiwei Liu, Shengchun Shen +5
Berry curvature plays a crucial role in exotic electronic states of quantum materials, such as intrinsic anomalous Hall effect. As Berry curvature is highly sensitive to subtle cha…
