That cancellation is demonstrated only inside the truncated effective Hamiltonian, while the integrals themselves extend to momenta where the truncation parameter is order one. This is a concrete, named gap rather than a demonstrated error. A numerical or analytical evaluation of the full quadratic theory would settle it.

(43). That effective Hamiltonian is derived by dropping all gradient terms in Eq. (40), specifically the terms of order Γ(ρ_b0/ρ_a0)k^2 and K k^4 relative to g. The paper's own hierarchy is |k| << 2π/ξ_c, with ξ_c = π sqrt(2Γ/g) in Model A and ξ_c = 2π sqrt(Γρ20^2/(gρ10)) in Model B. However, the correlation-function calculations integrate over |k| all the way up to the cutoff 2π/ξ_c. At that cutoff, the dropped Γ-term is of order Γ(2π/ξ_c)^2/g = O(1) (up to density ratios), so the integrand at the upper end of the integration domain lies outside the regime where Eq. (43) is controlled. In Model A, the saturation of the four-point correlation in d=2 relies on a delicate cancellation of the 1/|k|^2 (quadratic-mode) contributions between ⟨θ1θ1⟩, ⟨θ2θ2⟩, and ⟨θ1θ2⟩; this cancellation is explicitly shown only within the truncated Hamiltonian. If the retained gradient terms in Eq. (40) produce even a small symmetry-breaking admixture of the quadratic mode into the composite-order-parameter phase correlation, a logarithmic infrared divergence reappears and the claimed ODLRO degrades to quasi-long-range order. The same truncation underpins the linear mode used for Model Series B in Appendix C, so both advertised d=2 results inherit this sensitivity.

Two model series are constructed—Model Series A (hybridization of moments of the same order, with the concrete [d,1,2,2] model conserving the total dipole moments of two species) and Model Series B (hybridization of moments of different orders, with a concrete dipole-quadrupole model)—and for each the authors analyze the classical ground states, perform a harmonic (Bogoliubov) expansion about the condensate, diagonalize the effective Gaussian Hamiltonian, and compute two- and four-point correlation functions in d = 1, 2, 3. The central claims are: (i) in Model Series A in d = 2, the composite correlation ⟨Φ̂†₁(x)Φ̂₂(x)Φ̂₁(0)Φ̂†₂(0)⟩ saturates at long distances, spontaneously breaking the relative charge symmetry U(1)−,C with composite order parameter ⟨Φ̂₁Φ̂†₂⟩, and more generally partial breaking occurs in d = N+1 for the [d,N,m,m′] series; (ii) in Model Series B in d = 2, ⟨Φ̂†₁(x)Φ̂₁(0)⟩ saturates so the species-1 charge symmetry is spontaneously broken, while species 2 retains only power-law order.

This extends the fractonic-superfluid phenomenology of Refs. [43,44] in a non-trivial way and provides new instances for generalized Mermin-Wagner physics. The paper's strengths are that the results are derived analytically from the constructed Hamiltonians with no data fitting, the Bogoliubov diagonalization and T-matrix elements in Appendices A-D are detailed enough to be checked algebraically, the lattice constructions are explicit and respect the stated conservation laws, and the tilted-lattice realization gives a concrete experimental route.","major_comments":[{"comment":"The d = 2 ODLRO claim for Model Series A (saturation of ⟨Φ̂†₁(x)Φ̂₂(x)Φ̂₁(0)Φ̂†₂(0)⟩, Table III) is established only within the truncated Hamiltonian (43), obtained by dropping the gradient terms in the equation of motion (40) under the hierarchy |k| ≪ 2π/ξc of Eq. (42). The correlation integrals in Appendix B, e.g. Eqs. (B24)-(B31), are evaluated up to the cutoff 2π/ξc, where the dropped Γ(ρb0/ρa0)k² term is of the same order as the retained g term, so part of the integration domain lies outside the controlled regime. The saturation relies on the exact cancellation of the 1/|k|² (quadratic-mode) contributions among ⟨θ1θ1⟩, ⟨θ2θ2⟩ and ⟨θ1θ2⟩, and this cancellation is verified in Eqs. (B8)-(B31) only with the T-matrix of the truncated theory. Since the θ-sector matrix M2 is identical in the full Gaussian Hamiltonian (39) and in the truncated one (43) while only the π-sector M1 differs, the cancellation is expected to survive the π-sector gradients, but that argument is not given in the paper; the same truncation underpins the [d,N,m,m′] generalization of Sec.

In addition, the analytic evaluation (D33)-(D35) yields exponential decay of ⟨Φ̂†₂(x)Φ̂₂(0)⟩ in d = 2, which contradicts the 'power-law decay' entry in Table IV and the text after Eq. (D41); the numerical check at the single point x = 10^10 cannot distinguish these behaviors.

[43,44]), but the hybrid-moment constructions, the partial-symmetry-breaking results, and the lattice models are sufficiently new to warrant publication after a revision addressing the two major comments."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"Bottom line: this is a real extension of the fractonic-superfluid program, and the central d=2 ODLRO claims are probably right, even though the paper's own presentation makes the long-wavelength truncation look sketchier than it needs to be.\n\nWhat is new: hybrid conserved moments, built from moments of different species. The two model series are genuine additions to the literature. Model Series A gives partial symmetry breaking with a composite order parameter in d = N+1, and Model Series B does the same for a single species in d=2. The derivations are detailed and internally consistent. The Bogoliubov diagonalizations in the appendices are written out, the lattice models are explicitly constructed, and the tilted-lattice realization is worked out to third order. There is no data fitting; the only free parameter is the length scale ℓ, which just converts dimensions between different-order moments. The heavy citation of the authors' own prior papers is appropriate here: this is the third in a trilogy, and the framework genuinely builds on the first two.\n\nSoft spots are real but not fatal. The biggest one is the step from Eq. (40) to Eq. (43): the paper drops O(k²) terms in the π equation of motion and then integrates correlation functions up to the coherence-length cutoff, where those terms are O(1). I checked whether this threatens the d=2 saturation. For Model Series A it does not. The quadratic total-phase mode and the linear relative mode are orthogonal at k=0, and the admixture of the quadratic mode into the relative-phase correlation vanishes as O(k²), so the log divergence cannot reappear; the truncation only shifts the finite constant. The authors should state this explicitly, because as written the approximation looks uncontrolled. For Model Series B, the d=2 conclusion for species 1 relies on an angular-averaged upper bound plus numerical spot checks. The numerics are consistent and the bound is conservative, but a direct calculation with the full T-matrix would be cleaner. The mean-field phase diagram also assumes a positive quartic coefficient W without proof; that is minor.\n\nThis paper is for people working on generalized symmetries, multipole conservation, and quantum fluids. It gives them a new family of models and concrete predictions that could be tested in tilted-lattice Bose-Hubbard simulations. It deserves a serious referee, not a desk reject.
