Phonon mediated indirect spin interaction — •Pablo Reiser and Habib Rostami — University of Bath, Bath, United Kingdom

Due to the lack of inversion symmetry in the hBN monolayer, circular polarized vibration in solids, or chiral phonons, with nonzero angular momentum are allow. These chiral phonons can couple to spins of different nature through their angular momentum. Within this context, we explored the coupling of chiral phonons with non-zero angular momentum to two impurities spins in hBN. Using field theory methods, we obtained the spin susceptibility and studied it*s properties like the mass dependence of the coupling, frequency of oscillation and rate of decay. The momentum transfer due to this coupling may opens the door for non-trivial thermal or spin transport effects.
