Surface-acoustic-wave-induced unconventional superconducting pairing — •Viktoriia Kornich — Julius-Maximilians-Universität Würzburg
Exotic materials, topological states, and quantum collective phenomena are of high interest for fundamental science and technology, because they provide complex and stable performance even at a very small scale. The field of unconventional superconductivity investigates new features and phenomena occurring in superconducting materials and setups. However, the exact processes, which lead to unconventional superconducting states are usually not clear and subject to numerous hypotheses and attempts to experimentally verify them. Here, I will discuss how to use externally applied acoustic waves in order to induce unconventional superconducting pairing of different types in solid state matter, primarily in thin films and 2D materials. I will consider a simple setup consisting of a solid state material with conduction electrons and an applied surface acoustic wave, that breaks spatial translation symmetry. I will show that the symmetries of the possible surface-acoustic-wave-induced order parameters depend on the shape of the applied wave. As an example, I will show that even-frequency spin-triplet odd-parity order parameter can occur due to Rayleigh surface acoustic wave.
