Giant effective magnetic fields from optically driven chiral phonons in 4f paramagnets
We present a mechanism by which optically driven chiral phonon modes in rare-earth trihalides generate giant effective magnetic fields acting on the paramagnetic 4f spins. With cerium trichloride (CeCl_{3}) as our example system, we calculate the coherent phonon dynamics in response to the excitatio...
