Modifying the Electronic Orbitals of Nickelate Heterostructures Via Structural Distortions
Hanghui Chen, Divine P. Kumah, Ankit S. Disa +3
We describe a general materials design approach that produces large orbital energy splittings (orbital polarization) in nickelate heterostructures, creating a two-dimensional singl…
Dynamical control of orbital occupations via a ferroelectric-induced polar state in metallic manganites
Hanghui Chen, Qiao Qiao, Matthew S. J. Marshall +7
The breaking of orbital degeneracy on a transition metal cation and the resulting unequal electronic occupations of these orbitals provide a powerful lever over electron density an…
Engineering Correlation Effects via Artificially Designed Oxide Superlattices
Hanghui Chen, Chris A. Marianetti, Andrew J. Millis
Ab initio calculations are used to predict that a superlattice composed of layers of LaTiO3 and LaNiO3 alternating along the [001] direction is a S=1 Mott insulator with large magn…
