| contents | The identification of unconventional pairing in two-dimensional materials is a central challenge in modern condensed matter physics. While chiral p-wave superconductivity offers a promising platform for topological quantum computing, its detection remains elusive due to the inherent limitations of optical probes in the two-dimensional limit. We propose the anomalous acoustoelectric effect as a robust, alternative to optical signature of p-wave paring symmetry. We demonstrate that an acoustic wave induces a transverse dc current resulting in a measurable condensate phase difference on sample boundaries originating from the anisotropic scattering of quasiparticles in the absence of an external magnetic field. Crucially, the quasiparticle-mediated acoustoelectric response dominates near the critical temperature and, unlike the superconducting condensate, is not suppressed by electron-hole asymmetry factor. These results establish the anomalous acoustoelectric effect as a high-sensitivity electrical probe of the chiral order parameter, providing a tool for experimental detecting of unconventional pairing in superconductors. |
