Supercurrent-induced phonon angular momentum
arXiv:2604.12701 · doi:10.1103/mz1s-9z7k
Abstract
We propose a mechanism of supercurrent-induced phonon angular momentum in mixed parity superconductors and s-wave superconductors with spin orbit coupling. We derive analytical expressions of phonon angular momentum induced by the supercurrent by perturbative calculation. The physical interpretation of this effect is also discussed.
