Anomalous Spin Correlations and Mass-Generating Excitonic Instability of Interacting Weyl Fermions
Michihiro Hirata, Kyohei Ishikawa, Genki Matsuno +5
Recent advances in the study of nodal Weyl fermions (WFs), quasi-relativistic massless particles, constitute a novel realm of quantum many-body phenomena. The Coulomb interaction i…
Observation of an anisotropic Dirac cone reshaping and ferrimagnetic spin polarization in an organic conductor
Michihiro Hirata, Kyohei Ishikawa, Kazuya Miyagawa +6
The Coulomb interaction among massless Dirac fermions in graphene is unscreened around the isotropic Dirac points, causing a logarithmic velocity renormalization and a cone reshapi…
Edge States in Molecular Solid α-(BEDT-TTF)2I3: Effects of Electron Correlations
Yukiko Omori, Genki Matsuno, Akito Kobayashi
We examine the edge states of the Dirac electrons in the molecular material α-(BEDT-TTF)2I3 with electron-electron interactions. Based on the analysis of the extended Hubbard model…
