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…
