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…

Closing in on possible scenarios for infinite-layer nickelates: comparison of dynamical mean-field theory with angular-resolved photoemission spectroscopy
Liang Si, Eric Jacob, Wenfeng Wu +6
Conflicting theoretical scenarios for infinite-layer nickelate superconductors have been hotly debated, particularly regarding whether {only} a single Ni-3 band is rel…

Fermi and Luttinger arcs: two concepts, realized on one surface
Paul Worm, Matthias Reitner, Karsten Held +1
We present an analytically solvable model for correlated electrons, which is able to capture the major Fermi surface modifications occurring in both hole- and electron-doped cuprat…
