Composing Flow-Matching Energies with Known Physics: Generation, OOD Detection, and Inversion on PDE Fields

It is shown in this work that flow matching models with a potential-induced velocity yield an explicit scalar energy at all transport times, whose gradient is exactly the converted learned score and which recovers the marginal negative log-density at the population optimum.
