Query: Analysis of rippling in incommensurate one-dimensional coupled chains   Graphene and other recently developed 2D materials exhibit exceptionally
strong in-plane stiffness. Relaxation of few-layer structures, either
free-standing or on slightly mismatched substrates occurs mostly through
out-of-plane bending and the creation of large-scale ripples. In this work, we
present a novel double chain model, where we allow relaxation to occur by
bending of the incommensurate coupled system of chains. As we will see, this
model can be seen as a new application of the well-known Frenkel-Kontorova
model for a one-dimensional atomic chain lying in a periodic potential. We
focus in particular on modeling and analyzing ripples occurring in ground state
configurations, as well as their numerical simulation.
