A semiclassical tunneling model shows that two-field ultralight DM halos have stability bounds that can be relaxed for some density-mass ratios but become more stringent across much of the parameter space compared to single-field cases.
A first-principles Euclidean prescription for tunnelling rates out of Noether-charged states, including cases with non-trivial energy.
