Nanomechanical resonators have shown long lifetimes (Q > 10^9) and long coherence times, which makes them promising for quantum information applications as memories or transducers. However, their linear behaviour limits which quantum operations can be performed: An amplitude-dependent nonlinearity is necessary to realize a complete set of quantum gates. Recently, nanomechanical resonators have...

We study the collective behavior of a polar flock in an inhomogeneous environment in two dimensions. The inhomogeneity is modeled by introducing circular regions at random locations on the substrate with high noise, but accessible for the flock to move. Hence, inside such regions, the particles’ orientation gets randomized. Such inhomogeneities differ from physical disorder, which obstructs...
