Cotunneling theory and multiplet excitations: emergence of asymmetric line shape in inelastic scanning tunneling spectroscopy of correlated molecules on surfaces
Marco Lozano, Manish Kumar, Pavel Jelinek +1
Recent advances in on-surface chemistry, combined with scanning probe microscopy, have enabled the synthesis of correlated molecules on surfaces and the characterization of their c…
Strongly entangled Quantum Spin Rings driven by Hückel rule
Manish Kumar, Deng-Yuan Li, Zhangyu Yuan +11
Quantum spin rings represent an intriguing platform for studying unconventional magnetic order and exotic quantum phases, and they are also promising materials for emerging quantum…
Adsorption-induced surface magnetism
MiloÅ¡ BaljozoviÄ, Shiladitya Karmakar, André L. Fernandes Cauduro +8
We report the emergence of adsorption-induced magnetism from heterohelicene molecules on a non-magnetic Cu(100) surface. Spin-polarized low-energy electron microscopy (SP-LEEM) mea…
Breaking Peierls theorem in polyacetylene chains via topological design
Xinnan Peng, Marco Lozano, Jie Su +11
Peierls theorem postulates that a one-dimensional (1D) metallic chain must undergo a metal-to-insulator transition via lattice distortion, resulting in bond length alternation (BLA…
Designer polyradical nanographenes with strong spin entanglement and perturbation resilience via Clar's goblet extension
En Li, Manish Kumar, Xinnan Peng +9
Polyradical nanographenes featuring strong spin entanglement and robust many-body spin states against external magnetic perturbations not only enable the exploration of correlated…
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…
