Theory of atomic-scale direct thermometry using ESR-STM
Y. del Castillo, J. Fernández-Rossier
Knowledge of the occupation ratio and the energy splitting of a two-level system yields a direct readout of its temperature. Based on this principle, the determination of the tempe…
Gapless spin excitations in nanographene-based antiferromagnetic spin-1/2 Heisenberg chains
Chenxiao Zhao, Lin Yang, João C. G. Henriques +8
Haldane's seminal work established two fundamentally different types of excitation spectra for antiferromagnetic Heisenberg quantum spin chains: gapped excitations in integer-spin…
Building spin-1/2 antiferromagnetic Heisenberg chains with diaza-nanographenes
Xiaoshuai Fu, Li Huang, Kun Liu +13
Understanding and engineering the coupling of spins in nanomaterials is of central importance for designing novel devices. Graphene nanostructures with π-magnetism offer a chemical…
Non-resonant electric quantum control of individual on-surface spins
Santiago A. Rodríguez, Sergio S. Gómez, Joaquín Fernández-Rossier +1
Quantum control techniques play an important role in manipulating and harnessing the properties of different quantum systems, including isolated atoms. Here, we propose to achieve…
Tunable topological phases in nanographene-based spin-1/2 alternating-exchange Heisenberg chains
Chenxiao Zhao, Gonçalo Catarina, Jin-Jiang Zhang +8
Unlocking the potential of topological order within many-body spin systems has long been a central pursuit in the realm of quantum materials. Despite extensive efforts, the quest f…
Probing spin fractionalization with ESR-STM absolute magnetometry
Y. del Castillo, J. Fernández-Rossier
The emergence of effective spins at the edges of Haldane spin chains is one of the simplest examples of fractionalization. Whereas there is indirect evidence of this…
