D-wave Chiral Phonons from Electron-Phonon Coupling — •Dimos Chatzichrysafis¹ and Alexander Mook^{1, 2} — ¹Johannes Gutenberg Universität, Mainz — ²University of Münster

Chiral phononics, the field of study of phonons carrying finite orbital angular momentum has recently attracted wide interest due to its rich, versatile physics and potential applications.

In search of mechanisms to generate unconventional phonon orbital angular momentum textures, we demonstrate theoretically that d-wave chiral phonons can emerge even in the absence of electronic spin order. We show that by considering an electronic system hosting a d-wave orbital angular momentum texture, non-relativistic electron-phonon coupling leads to the formation of d-wave chiral phonons.

In this way we expand the potential platforms of chiral phononics and offer application routes unique to d-wave textures, such as orbital phonon splitters.
