Modulated Dirac bands and integer hopping ratios in a honeycomb lattice of phenalenyl-tessellation molecules
Naoki Morishita, Kenshin Komatsu, Motoharu Kitatani +1
A family of nanographene molecules called phenalenyl-tessellation molecules (PTMs) exhibits two types of zero modes: a type that spreads over the entire…
Designing a polymerized phenalenyl tessellation molecule to realize a super-honeycomb antiferromagnetic S = 3/2 spin system
Kenshin Komatsu, Naoki Morishita, Motoharu Kitatani +1
In a multiply hydrogenated polymer of phenalenyl tessellation molecules (PTMs), spatially overlapping zero modes appear, and three spin-aligned electron spins per PTM are generated…
Zero-energy modes in super-chiral nanographene networks of phenalenyl-tessellation molecules
Naoki Morishita, Koichi Kusakabe
We have derived a general rule for the appearance of zero-energy modes in super-chiral defective nanographene. This so-called "super-zero-sum rule" defines the appearance of zero m…
Theoretical Analysis on Pseudo-Degenerate Zero-Energy Modes in Vacancy-Centered Hexagonal Armchair Nanographene
Naoki Morishita, Gagus Ketut Sunnardianto, Satoaki Miyao +1
Deriving mathematical expressions of two zero modes for a -band tight-binding model, we identify a class of bipartite graphs having the same number of subgraph sites, where each…
Magnetic correlation effects by the topological zero mode in a hydrogenated graphene vacancy
Naoki Morishita, Gagus Ketut Sunnardianto, Koichi Kusakabe +3
Electron correlation effects caused by the topological zero mode of a hydrogenated graphene vacancy, , with three adsorbed hydrogen atoms is discussed theoretically. A Kon…
