Frustrated magnetic interactions in a cyclacene crystal
R. Ortiz, J. C. Sancho-García, J. Fernández-Rossier
We study the emergence of magnetism and its interplay with structural properties in a two dimensional molecular crystal of cyclacenes, using density functional theory (DFT). Isolat…
Observation of fractional edge excitations in nanographene spin chains
Shantanu Mishra, Goncalo Catarina, Fupeng Wu +9
Fractionalization is a phenomenon in which strong interactions in a quantum system drive the emergence of excitations with quantum numbers that are absent in the building blocks. O…
Renormalization of spin excitations and Kondo effect in open shell nanographenes
David Jacob, Ricardo Ortiz, Joaquín Fernández-Rossier
We study spin excitations and Kondo effect in open-shell nanographenes, motivated by recent scanning tunneling inelastic spectroscopy experiments. Specifically, we consider three s…
A superlattice approach to doping infinite-layer nickelates
R. A. Ortiz, H. Menke, F. Misják +8
The recent observation of superconductivity in infinite-layer NdSrNiO thin films has attracted a lot of attention, since this compound is electronically and structu…
