‘Giant atom’ physics occurs when the size of the atomic system becomes comparable to the wavelength of the light it interacts with. For atoms, such a regime is impossible to reach, however, for artificial atomic systems such ‘giant atom’ physics can be explored. Here, Wang et al demonstrate giant spin ensembles, consisting of magnetic spheres coupled to a microwave waveguide.
