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…
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…
Tailoring magnetism of nanographenes via tip-controlled dehydrogenation
Chenxiao Zhao, Qiang Huang, Leoš Valenta +10
Atomically precise graphene nanoflakes, called nanographenes, have emerged as a promising platform to realize carbon magnetism. Their ground state spin configuration can be anticip…
