Spin excitations in the quasi-two-dimensional charge-ordered insulator -(BEDT-TTF)I probed via C NMR
Kyohei Ishikawa, Michihiro Hirata, Dong Liu +3
The spin excitations from the nonmagnetic charge-ordered insulating state of -(BEDT-TTF)I at ambient pressure have been investigated by probing the static and low-freque…
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…
Insulating nature of strongly correlated massless Dirac fermions in an organic crystal
Dong Liu, Kyohei Ishikawa, Ryosuke Takehara +3
Through resistivity measurements of an organic crystal hosting massless Dirac fermions with a charge-ordering instability, we reveal the effect of interactions among Dirac fermions…
