Abstract: (APS)

The quantum theory of fields is largely based on studying perturbations around noninteracting, or free, field theories, which correspond to a collection of quantum-mechanical harmonic oscillators. The quantum theory of an ordinary fluid is “freer”, in the sense that the noninteracting theory also contains an infinite collection of quantum-mechanical free particles, corresponding to vortex modes. By computing a variety of correlation functions at tree and loop level, we give evidence that a quantum perfect fluid can be consistently formulated as a low-energy, effective field theory. We speculate that the quantum behavior is radically different from both classical fluids and quantum fields.

it seems to us that the divergence of tree-level S-matrix elements is a more fundamental problem per se

Considering invariants was suggested in [4], but was not followed up

If M is a torus, for example, this can be arranged by ensuring that the Fourier modes above the EFT cut-off fall off faster than any polynomial
