Unifying microscopic theories for the phono-magnetic effect
Natalia Shabala, Finja Tietjen, Ylva Liljegren +1
Phonon angular momentum induces an effective magnetic field, a phenomenon called phono-magnetic effect, which has been measured to vary significantly in size. Here, we compare thre…

Axial phono-magnetic effects
Natalia Shabala, Finja Tietjen, R. Matthias Geilhufe
Axial or circularly polarized phonons are collective lattice vibrations with angular momentum. Over the past decade they have emerged as a promising mechanism for the manipulation…

Phonon Inverse Faraday effect from electron-phonon coupling
Natalia Shabala, R. Matthias Geilhufe
The phonon inverse Faraday effect describes the emergence of a DC magnetization due to circularly polarized phonons. In this work we present a microscopic formalism for the phonon…
