Bosonic and Fermionic love number of static acoustic black hole

We compute static ($\omega \to 0$) tilde Love numbers for scalar ($s=0$) and Dirac ($s=1\mathrm{/}2$) perturbations of static acoustic black holes (ABHs) in (3+1) and (2+1) dimensions respectively. By imposing horizon regularity condition and matching to the large-radius expansion, we extract the ratio between decaying and growing modes. It turns out that in (3+1) dimensions the scalar Love number is generically nonzero for ABHs, while the Fermionic Love numbers follow a universal power-law form $F_{\mathrm{\ell }m}^{\pm 1\mathrm{/}2}=\pm 4^{-(\mathrm{\ell }+1\mathrm{/}2)}$. In (2+1) dimensions the scalar field exhibits a strange logarithmic structure, causing the Bosonic Love number to vanish for even $m$ but remain nontrivial for odd $m$; In contrast, the Fermionic Love number in this case retains a simple power-law form $F_m=4^{-m}$ and is generically nonzero. These results provide insights into tidal response in analogue gravity systems and highlight qualitative differences between integer- and half-integer-spin fields.
