Query: Kinks and antikinks of buckled graphene: A testing ground for phi^4
  field model   Kinks and antikinks of the classical phi^4 field model are topological
solutions connecting its two distinct ground states.
  Here we establish an analogy between the excitations of a long graphene
nanoribbon buckled in the transverse direction and phi^4 model results. Using
molecular dynamics simulations, we investigated the dynamics of a buckled
graphene nanoribbon with a single kink and with a kink-antikink pair. Several
features of phi^4 model have been observed including the kink-antikink capture
at low energies, kink-antikink reflection at high energies, and a bounce
resonance. Our results pave the way towards the experimental observation of a
rich variety of phi^4 model predictions based on graphene.
