Abstract
Cold-atom analogue experiments are a promising new tool for studying relativistic vacuum decay, allowing us to empirically probe early-Universe theories in the laboratory. However, existing analogue proposals place stringent requirements on the atomic scattering lengths that are challenging to realize experimentally. Here we generalize these proposals and show that any stable mixture between two states of a bosonic isotope can be used as a relativistic analogue. This greatly expands the range of suitable experimental setups, and will thus expedite efforts to study vacuum decay with cold atoms.
