Beyond spin models in orbitally-degenerate open-shell nanographenes
J. C. G. Henriques, D. Jacob, A. Molina-Sánchez +3
The study of open-shell nanographenes has relied on a paradigm where spins are the only low-energy degrees of freedom. Here we show that some nanographenes can host low-energy exci…

Designer spin models in tunable two-dimensional nanographene lattices
J. C. G. Henriques, Mar Ferri-Cortés, J. Fernández-Rossier
Motivated by recent experimental breakthroughs, we propose a strategy to design two-dimensional spin lattices with competing interactions that lead to non-trivial emergent quantum…
