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
Miloš Baljozović, 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 modi…
Magnetic ground state discrimination of a Polyradical Nanog-raphene using Nickelocene-Functionalized Tips
Diego Soler-Polo, Oleksandr Stetsovych, Manish Kumar +11
Molecular magnets are a promising class of materials with exciting properties and applications. However, a profound understanding and application of such materials depends on the a…
Theoretical model for multi-orbital Kondo screening in strongly correlated molecules with several unpaired electrons
Aitor Calvo-Fernández, Manish Kumar, Diego Soler-Polo +3
The mechanism of Kondo screening in strongly correlated molecules with several unpaired electrons on a metal surface is still under debate. Here, we provide a theoretical framework…
Multi-orbital Kondo screening in strongly correlated polyradical nanographenes
Aitor Calvo-Fernández, Diego Soler-Polo, Andrés Pinar Solé +9
We discuss coexistence of Kondo and spin excitation signals in tunneling spectroscopy in strongly correlated polyradical -magnetic nanographenes on a metal surface. The Kondo si…
Significance of nuclear quantum effects in hydrogen bonded molecular chains
Aleš Cahlík, Jack Hellerstedt, Jesús I. Mendieta-Moreno +10
In hydrogen bonded systems, nuclear quantum effects such as zero-point motion and tunneling can significantly affect their material properties through underlying physical and chemi…
Coupled Sublattice Melting and Charge-Order Transition in Two Dimensions
Tyler S. Smith, Fangfei Ming, Daniel González Trabada +5
Two-dimensional melting is one of the most fascinating and poorly understood phase transitions in nature. Theoretical investigations often point to a two-step melting scenario invo…
