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…
The role of precursor coverage in the synthesis and substrate transfer of graphene nanoribbons
Rimah Darawish, Oliver Braun, Klaus Muellen +4
Graphene nanoribbons (GNRs) with atomically precise widths and edge topologies have well-defined band gaps that depend on ribbon dimensions, making them ideal for room-temperature…
Electronic decoupling and hole-doping of graphene nanoribbons on metal substrates by chloride intercalation
Amogh Kinikar, Thorsten G. Englmann, Marco Di Giovannantonio +14
Atomically precise graphene nanoribbons (GNRs) have a wide range of electronic properties that depend sensitively on their chemical structure. Several types of GNRs have been synth…
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…
Charge State-Dependent Symmetry Breaking of Atomic Defects in Transition Metal Dichalcogenides
Feifei Xiang, Lysander Huberich, Preston A. Vargas +11
The functionality of atomic quantum emitters is intrinsically linked to their host lattice coordination. Structural distortions that spontaneously break the lattice symmetry strong…
