Acknowledgments We would like to cordially thank Leszek J. Spalek from the Cavendish Laboratory, Cam- bridge, for suggesting the problem and numerous discussions, as well as for his critical reading of the manuscript. The work was supported by the Grant No. NN 202 128 736 from Ministry of Science and Higher Education. If we assume that the fluctuations do not change rapidly in space then we can estimate their local value in terms of their Fourier components: where k = ξ ⃗ k . We also assume that e i ⃗ k · ⃗ r satisfies periodic boundary conditions. After substituting (A1) and (A2) into (41): Taking into consideration that ∫ d $^{3}$re i ( k + q ) · r = δ$_{k}$$_{,}$$_{-q}$ and after rewriting the last term as: 23 ∑ k ∑ q δm$_{k}$δp$_{q}$δ$_{k}$$_{,}$$_{-q}$ = 1 2 [ ∑ k δm$_{k}$δp$_{-k}$ + ∑ q δm$_{-q}$δp$_{q}$$^{]}$ (A4) = 1 2 ∑ k [ δm$_{k}$δp$_{-k}$ + δm$_{-k}$δp$_{k}$ ] , δp ( r ) = ∑ k δp$_{k}$e i k · $^{r}$, (A1) δm ( r ) = ∑ k δm$_{k}$e i k · $^{r}$, (A2) Appendix A: Partition function with inclusion of Gaussian fluctuations δF = C$_{m}$γ$_{me}$ ∑ k ∑ q δm$_{k}$δp$_{q}$$^{∫}$ d $^{3}$r e i ( k + q ) · r (A3) + C$_{m}$ ∑ k ∑ q [ B$_{m}$ − 1 2 k · q$^{]}$ δm$_{k}$δm$_{q}$$^{∫}$ d $^{3}$r e i ( k + q ) · r + C$_{m}$ ∑ k ∑ q [ A$_{m}$ − 1 2 a$_{3}$ k · q$^{]}$ δp$_{k}$δp$_{q}$$^{∫}$ d $^{3}$r e i ( k + q ) · $^{r}$.
