Abstract: The nuclear matrix elements for the momentum quadrupole operator are important for the interpretation of precision atomic physics experiments that search for violations of Lorentz symmetry. We use the configuration-interaction nuclear shell model and self-consistent mean field theory to calculate these matrix elements in Ne-21. These are the first microscopic calculations for the momentum quadrupole tensor that go beyond the single-particle estimate. We show that the momentum matrix elements are strongly suppressed by the many-body correlations, in contrast to the well known enhancement of the spatial quadrupole nuclear matrix elements.
