Luttinger surface and exchange splitting induced by ferromagnetic fluctuations
Motoharu Kitatani, Yusuke Nomura, Shiro Sakai +1
Ferromagnetism in the single-orbital Hubbard model, which contains only local Coulomb repulsion and no explicit ferromagnetic exchange interactions, has been extensively studied. H…
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…
Exploration of the potential energy surface for the conformational interconversion of the amyloid peptide at the fibril end
Yasuhiro Oishi, Motoharu Kitatani, Kichitaro Nakajima +2
The formation of amyloid fibrils comprising amyloid (A) peptides is associated with the pathology of Alzheimer's disease. In this study, we theoretically investigated the A$…
Interplay of Pomeranchuk instability and superconductivity in the two-dimensional repulsive Hubbard model
Motoharu Kitatani, Naoto Tsuji, Hideo Aoki
Interplay of Pomeranchuk instability (spontaneous symmetry breaking of the Fermi surface) and d-wave superconductivity is studied for the repulsive Hubbard model on the square latt…
