Quantum simulations based on near-resonance Bose gases are limited by their
short lifetimes due to severe atom losses. In addition to this, the recently
predicted thermodynamical instability adds another constraint on accessing the
resonant Bose gases. In this Letter, we offer a potential solution by proposing
long-lived resonant Bose gases in both two and three dimensions, where the
conventional few-body losses are strongly suppressed. We show that the
thermodynamical properties as well as the lifetimes of these strongly
interacting systems are universal, and independent of short-range physics.Comment: 5 page
