Title: Effects of Lorentz-symmetry violation on the spectra of rare-earth ions in a crystal field

Here, we demonstrate that experiments measuring the transition energies of rare-earth ions doped in crystalline lattices are sensitive to violations of local Lorentz invariance and Einstein's equivalence principle. Using the crystal field of LaCl 3 as an example, we calculate the frame-dependent energy shifts of the transition frequencies between low-lying states of Ce 3+, Nd 3+, and Er 3+ dopants in the context of the standard model extension, and show that they have high sensitivity to electron anomalies that break rotational invariance.
