Orbital character and photoemission signatures of the A-pocket in infinite-layer nickelates
Leonard M. Verhoff, Michael Seidl, Liang Si +1
The orbital character of the so-called -pocket in infinite-layer nickelates remains under debate. We investigate bulk NdNiO using density-functional theory combined with dyn…
Beyond the conventional Emery model: crucial role of long-range hopping for cuprate superconductivity
Eric Jacob, M. O. Malcolms, Viktor Christiansson +6
The Emery model is the quintessential model for cuprate superconductors. In his eponymous paper, Emery only considered the next-nearest-neighbor oxygen-copper hopping. Later, also…
Pressure induced redistribution of oxygen hole states in LaNiO
Guiwen Jiang, Liang Si, George A. Sawatzky +1
Using density functional calculations and multi-orbital, multi-atom cluster exact diagonalization that includes local exchange and Coulomb interactions, we explored the local low-e…
A route to room temperature ferromagnetic ultrathin SrRuO films
Liang Si, Zhicheng Zhong, Jan M. Tomczak +1
Experimental efforts to stabilize ferromagnetism in ultrathin films of transition metal oxides have so far failed, despite expectations based on density functional theory (DFT) and…
