Identification and optimization of accurate spin models for Fermi-Hubbard ladders using matrix product states
Andoni Agirre, Thomas Frederiksen, Geza Giedke +1
Open-shell nanographenes offer a controlled setting to study correlated magnetism emerging from -electron systems. Here, we study non-bipartite Fermi-Hubbard ladders describing…
Topological Engineering of a Frustrated Antiferromagnetic Triradical in Aza-Triangulene Architectures
Francisco Romero-Lara, Manuel Vilas-Varela, Ricardo Ortiz +19
Open-shell nanographenes provide a versatile platform to host unconventional magnetic states within their π-conjugated networks. Particularly appealing are graphene architectures t…
Single-molecule electroluminescence: crossover from weak to strong coupling
Andrés Bejarano, Moritz Frankerl, Rémi Avriller +2
We develop a microscopic model to investigate current-induced light emission in single-molecule tunnel junctions, where a two-level system interacts with a plasmonic field. Using t…
Spin and Charge Control of Topological End States in Chiral Graphene Nanoribbons on a 2D Ferromagnet
Leonard Edens, Francisco Romero Lara, Trisha Sai +5
Tailor-made graphene nanostructures can exhibit symmetry-protected topological boundary states that host localized spin- moments. However, one frequently observes charge trans…
On-surface Synthesis of a Ferromagnetic Molecular Spin Trimer
Alessio Vegliante, Manuel Vilas-Varela, Ricardo Ortiz +12
Triangulenes are prototypical examples of open-shell nanographenes. Their magnetic properties, arising from the presence of unpaired electrons, can be extensively tuned by mod…
Substrate stabilization of Jahn-Teller distortion in a single molecule
Moritz Frankerl, Laerte L. Patera, Felix Giselbrecht +3
Charge-state transitions of a single Cu-phthalocyanine molecule adsorbed on an insulating layer of NaCl on Cu(111) are probed by means of alternate charging scanning tunneling micr…
