a, Calculated band structure of tBLG modeled by a continuum model. b, Corresponding low energy band structure in (a). The red, black and blue arrows indicate interband transition between multiple van Hove singularities with energy of 0.08 eV, 0.11 eV and 0.16 eV. c, d, Calculated longitude (c) and transverse (d) optical conductivity of tBLG. Grey and red curves represent imaginary and real part, respectively.
