Role of Interlayer Electron Hopping for Spin Density Wave State in the Zero-Gap Organic Conductor

Shinya Katayama, Akito Kobayashi, Yoshikazu Suzumura

We investigate the formation of density waves in the zero-gap state (ZGS) which has been found in the quasi-two-dimensional organic conductor $\alpha$-(BEDT-TTF)${}_2$I${}_3$ salt under the…
