Optical phonons in doped Dirac materials acquire a magnetic moment from the electron fluid's Hall viscosity through an emergent frame (gravitational) field coupling, matching measured values in Cd3As2.
This quadrupolar component shares the same tensorial form as a nematic order parameter, capturing an elliptic distortion of the Fermi surface
