As highly tunable platforms with exotic rich phase diagrams, moiré materials have captured the hearts and minds of physicists. Moiré materials arise when 2D crystal layers are stacked at relative twists. Their almost periodicity and multiscale behavior make these materials particularly mathematically appealing. We will describe the challenges in establishing a framework to study (phonon/vibrational) wave propagation in these materials, and explain how to overcome them.
