- Abstract: We study a phononic crystal interacting with an artificial atom { a
superconducting quantum system { in the quantum regime. The phononic crystal is
made of a long lattice of narrow metallic stripes on a quatz surface. The
artificial atom in turn interacts with a transmission line therefore two
degrees of freedom of different nature, acoustic and electromagnetic, are
coupled with a single quantum object. A scattering spectrum of propagating
electromagnetic waves on the artificial atom visualizes acoustic modes of the
phononic crystal. We simulate the system and found quasinormal modes of our
phononic crystal and their properties. The calculations are consistent with the
experimentally found modes, which are fitted to the dispersion branches of the
phononic crystal near the first Brillouin zone edge. Our geometry allows to
realize effects of quantum acoustics on a simple and compact phononic crystal.
