A new implementation of stochastic many-body perturbation theory for periodic2D systems is presented. The method is used to compute quasiparticleexcitations in twisted bilayer phosphorene. Excitation energies are studiedusing stochastic $G_0W_0$ and partially self-consistent $\bar \Delta GW_0$approaches. The approach is inexpensive; it is used to study twisted systemswith unit cells containing $>2,700$ atoms ($>13,500$ valence electrons), whichcorresponds to a minimum twisting angle of $\approx 3.1^\circ$. Twistedbilayers exhibit band splitting, increased localization and formation oflocalized Moir\'e impurity states, as documented by band-structure unfolding.Structural changes in twisted structures lift band degeneracies. Energies ofthe impurity states vary with the twisting angle due to an interplay betweennon-local exchange and polarization effects. The mechanisms of quasiparticleenergy (de)stabilization due to twisting are likely applicable to a wide rangeof low-dimensional Moir\'{e} superstructures.
