Fluctuation-frustrated flat band instabilities in NdNiO_{2}

The discovery that Nd_{1−x}Sr_{x}NiO_{2}, with the CaCuO_{2} infinite-layer structure, superconducts up to 15 K around the hole-doping level x=0.2 raises the crucial question of its fundamental electronic and magnetic processes. The unexplained basic feature that we address is that, for x=0 and as o...
