Claims

C1strongest claim

nucleation is governed by a nonequilibrium quasi-potential rather than the reversible work of formation. Surprisingly, because of the reduced hyperuniform fluctuations, the nucleation probability no longer separates into the usual surface and volume contributions. Furthermore, accounting for capillary waves reveals a clear breakdown of detailed balance driven by nonreciprocal dynamics.

C2weakest assumption

The projection of the full density-field dynamics onto a small set of collective variables is sufficient to capture the essential nucleation and capillary-wave statistics without missing relevant modes or introducing uncontrolled approximations.

C3one line summary

In hyperuniform active fluids, nucleation is governed by a nonequilibrium quasi-potential with nucleation probability not separating into surface and volume terms, while capillary waves exhibit breakdown of detailed balance from nonreciprocal dynamics.
