Time-evolution patterns of electrons in twisted bilayer graphene

We characterize the dynamics of electrons in twisted bilayer graphene by analyzing the time evolution of electron waves in an atomic lattice. We perform simulations based on a kernel polynomial technique using Chebyshev polynomials; this method does not requires any diagonalization of the system Ham...
