Emergence of Dirac Electron Pair in Charge Ordered State of Organic Conductor $\alpha$-(BEDT-TTF)${}_2$I${}_3$

A. Kobayashi, Y. Suzumura, F. Piéchon +1

We re-examine the band structure of the stripe charge ordered state of $\alpha$-(BEDT-TTF)${}_2$I${}_3$ under pressure by using an extended Hubbard model within the Hartree mean-field theor…
