Bobkingite, a new coupled sawtooth chain platform
P. Peter Stavropoulos, Aleksandar Razpopov, Harrison LaBollita +3
We investigate the mineral bobkingite, \ce{Cu5(OH)8Cl2(H2O)2}, as a potential realization of the sawtooth chain. Using \textit{ab initio} methods, we estimate the magnetic exchange…
Squeezing dynamical singlets in bilayer nickelates
Harrison LaBollita, Andrew J. Millis, Olivier Gingras
We present realistic calculations within the density functional plus cluster dynamical mean-field formalism indicating that the physics of the the bilayer Ruddlesden-Popper nickela…
Electron vs. hole doping in infinite-layer nickelates: electronic structure, magnetism and correlations
Ezra Day-Roberts, Fabio Bernardini, Harrison LaBollita +3
The observation of superconductivity in undoped infinite-layer nickelates NiO ( = rare earth) challenges our current understanding and calls for a re-examination of the u…
Contrasting Spin Excitations in Octahedral and Square-Planar n=8 Ruddlesden-Popper Nickelates
K. Scott, H. LaBollita, G. A. Pan +15
The discovery of superconductivity in reduced square-planar nickelates marked a major advance in identifying structural and electronic analogs to the high- cuprates. The more…
Superconducting phase diagram of multi-layer square-planar nickelates
Grace A. Pan, Dan Ferenc Segedin, Sophia F. R. TenHuisen +21
The discovery of superconductivity in square-planar nickelates has offered a rich materials platform to explore the origins of cuprate-like superconductivity. Experimental investig…
