Superconducting circuits can be used as artificial atoms and we will discuss how they can be used to study new physics. Specifically, I will show how artificial atoms can be used to study vacuum fluctuations by placing the atom in front of a mirror.
I will also show how these atoms can be connected to sound so that they decay by emitting individual phonons instead of individual photons. Sound-coupled atoms can also function as giant atoms, leading to new physics like non-exponential relaxation.
