  We discuss the possibility to create hybrid quantum systems that combine
ultracold atoms with graphene membranes. We investigate a setup in which a cold
atom cloud is placed close to a free-standing sheet of graphene at distances on
the order of a few hundred nanometers. The atoms then couple to the graphene
membrane via Casimir-Polder forces. Temporal changes in the atomic state of the
atomic cloud changes the Casimir-Polder interaction, thereby leading to the
creation of a backaction force in the graphene sheet. This setup provides a
controllable way to engineer ripples in a graphene sheet.
