Controlling the emission and interaction properties of quantum emitters (QEs)\nembedded within an optical cavity is a key technique in engineering\nlight-matter interactions at the nanoscale, as well as in the development of\nquantum information processing. State-of-the-art optical cavities are based on\nhigh Q photonics crystals and dielectric resonators. However, wealthier\nresponses might be attainable with cavities carved in more exotic materials.\nHere, we theoretically investigate the emission and interaction properties of\nQEs embedded in open epsilon-near-zero (ENZ) cavities. Using analytical methods\nand numerical simulations, it is demonstrated that open ENZ cavities present\nthe unique property of supporting nonradiating modes independently of the\ngeometry of the external boundary of the cavity (shape, size, topology...).\nMoreover, the possibility of switching between radiating and nonradiating modes\nenables a dynamic control of both the emission by, and the interaction between,\nQEs. These phenomena provide unprecedented degrees of freedom in controlling\nand trapping fields within optical cavities, as well as in the design of cavity\nopto- and acousto-mechanical systems.\n
