## Description

- description: "We propose twisted homobilayer of a carbon allotrope, C568, to be
    a promising platform to realize a controllable square lattice single-band extended
    Hubbard model. This setup has the advantage of a widely tunable \U0001D461′/\U0001D461
    ratio without adding external fields, and the intermediate temperature \U0001D461≪\U0001D447≪\U0001D448
    regime can be easily achieved. We first analyze the continuum model obtained from
    symmetry analysis and first-principle calculations, and calculate the band structures.
    Subsequently, we derive the corresponding tight-binding models and fit the hopping
    parameters as well as the Coulomb interactions. When a displacement field is applied,
    anisotropic nearest-neighbor hoppings can further be achieved. If successfully
    fabricated, the device could be an important stepping stone towards understanding
    high-temperature superconductivity."
