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.

Simulations reveal tidal heating dominates stellar cluster evolution in low-mass fuzzy dark matter halos, suppressed by reduced soliton mass and tidal stripping, so halo structure must be modeled to constrain the fuzzy dark matter particle mass.

Tunneling and tidal stripping in multifield ultralight dark matter halos
