Abstract
Unconventional superconductivity is usually associated with symmetry breaking in the system. Here we consider a simple setup consisting of a solid state material with conduction electrons and an applied surface acoustic wave (SAW), that can break time and spatial translation symmetries. We study the symmetries of the possible SAW-induced order parameters, showing that even-frequency spin-triplet odd-parity order parameter can occur. We suggest different methods of how to engineer the symmetries of the order parameters using SAWs and the applications of such setups.

Report
The main merit of this paper lies in stimulating experimental research, as it shows how pairing interaction in the odd-parity pairing channel can be induced by driving surface acoustic wave even when there is no low energy odd-parity phonon present in the material. The author's aim is limited, however, by the fact that it neither present specific material candidates nor seeks to analyze competition between different possible superconducting phases. In that sense, the paper seems more suitable to SciPost Physics Core.
