A new frictional mechanism, based on collective stick-slip motion of moiré superstructures across polycrystalline two-dimensional material interfaces, is predicted. The dissipative stick-slip behavior originates from an energetic bistability between low- and high-commensurability configurations of l…

The interaction between distinct excitations in solids is of both fundamental interest and technological importance. The layered magnetic semiconductor CrSBr exhibits strong coupling between excitons and coherently hybridized magnons, where both magnetic fields and strain can tune the coupling precisely.
