Spin State Disproportionation in Insulating Ferromagnetic LaCoO3 Epitaxial Thin Films
Shanquan Chen, Jhong-Yi Chang, Qinghua Zhang +14
The origin of insulating ferromagnetism in epitaxial LaCoO3 films under tensile strain remains elusive despite extensive research efforts have been devoted. Surprisingly, the spin…
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…
Pressure-induced superconductivity reentrant in transition metal dichalcogenide TiSe2
Wei Xia, Jiaxuan Wu, Zhongyang Li +15
Through either elements intercalation or application of pressure, transition metal dichalcogenide 1T-TiSe2 exhibits superconductivity in proximity to a charge density wave (CDW) qu…
Dynamical Mean Field Studies of Infinite Layer Nickelates: Physics Results and Methodological Implications
Hanghui Chen, Alexander Hampel, Jonathan Karp +2
This article summarizes recent work on the many-body (beyond density functional theory) electronic structure of layered rare-earth nickelates, both in the context of the materials…
Pressure-induced metal-insulator transition in oxygen-deficient LiNbO-type ferroelectrics
Chengliang Xia, Yue Chen, Hanghui Chen
Hydrostatic pressure and oxygen vacancies usually have deleterious effects on ferroelectric materials because both tend to reduce their polarization. In this work we use first-prin…
