N2 - Moiré patterns are omnipresent. They are important for any
overlapping periodic phenomenon, from vibrational and electromagnetic,
to condensed matter. Here we show, both theoretically and via
experimental simulations by ultracold atoms, that for one-dimensional
finite-size periodic systems, moiré patterns give rise to
anomalous features in both classical and quantum systems. In contrast to
the standard moiré phenomenon, in which the pattern periodicity
is a result of a beat-note between its constituents, we demonstrate
moiré patterns formed from constituents with the same
periodicity. Surprisingly, we observe, in addition, rigidity and
singularities. We furthermore uncover universal properties in the
frequency domain, which might serve as a novel probe of emitters. These
one-dimensional effects could be relevant to a wide range of periodic
phenomena.
