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…
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…
Magnetically-driven orbital-selective insulator-metal transition in double perovskite oxides
Hanghui Chen
Interaction-driven metal-insulator transitions or Mott transitions are widely observed in condensed-matter systems. In multi-orbital systems, many-body physics is richer in which a…
Charge transfer driven emergent phenomena in oxide heterostructures
Hanghui Chen, Andrew J. Millis
Complex oxides exhibit many intriguing phenomena, including metal-insulator transition, ferroelectricity/multiferroicity, colossal magnetoresistance and high transition temperature…
