Electric field on nucleus in solids and interaction of CP-violating nuclear electric dipole moment with phonons
In atoms and molecules, electrons screen the nucleus from the external electric field. However, if the frequency of the electric field reaches the energy of atomic or molecular transition, the electric field at the nucleus may be resonantly enhanced by many orders in magnitude.

| Summary: | In atoms and molecules, electrons screen the nucleus from the external electric field. However, if the frequency of the electric field reaches the energy of atomic or molecular transition, the electric field at the nucleus may be resonantly enhanced by many orders in magnitude. In this paper, we study the mechanisms of screening or enhancement of electric field acting on the nuclei in solid states. We show that in dielectric crystals the phonon oscillations of the lattice play a crucial role for determining the electric field on nuclei within the MHz–THz region. As an application, we propose an experimental scheme for measuring the CP-violating nuclear electric dipole moment in a solid state based on the coherent excitation of acoustic phonons. |
