Fig. 2: Real space representation of the center-of-mass wavefunction of the first excitonic states.

a Top curve: absolute value of the center-of-mass (COM) wavefunction Ψ for the first COM IX eigenstate along the crystallographic direction of a reconstructed bilayer at 1.3° twist angle as shown in Fig. 1c. Bottom curve: Corresponding total IX potential along the same direction. The arrow indicates one of many small variations of Vtot caused by the introduced imperfections within the simulated sample. b–d Absolute value of the COM wavefunction of the first three IX eigenstates in real space. The dashed red line in (b) corresponds to the x-axis in (a).
