and electric polarizabilities from lattice QCD simulated in background electric fields. Using anisotropic gauge configurations with dynamical clover fermions, we perform such computa- tions. In Appendix B, we obtain results for the neutron using upolarized lattice correlation functions. Such results, however, do not allow one to determine the electric polarizability— only a combination of the electric polarizability and the square of the magnetic moment. The separation of these terms (which is analogous to accounting for Born-level contributions in the Compton scattering amplitude, see Appendix A) requires treatment of baryon spin, which is afforded by studying boost-projected correlators. Our analysis of boost-projected lattice correlation functions demonstrates that nucleon magnetic moments and electric po- larizabilities can be extracted from lattice calculations in background electric fields. This applies to both the neutron and proton. There are a number of possible refinements of our computation that would reduce the systematic uncertainties. Currently, our calculations are limited to electrically neutral sea quarks, and there is a need to remedy this situation. Furthermore, studies on larger volumes will not only reduce finite volume effects, but allow the implementation of smaller values of the quantized external field strength. Calculations at various values of the quark mass will allow for chiral extrapolations to make contact with the physical QCD point. We intend to carry out this work in the future. Finally, our approach can be used to study the magnetic moments and electric polarizabilities of the remaining members of the baryon octet.

Motion-induced electric dipole moments underly the Born-like terms encountered above. These Born couplings are magnetic in origin, and their subtraction is required to arrive at physical electric polarizabilities. Born subtractions are carried out when analyzing experimental data, calculating polarizabilities from chiral perturbation theory; and, unique to this work, determining electric polarizabilities from lattice QCD. Here we remind the reader of the physics underlying the Born subtraction. For simplicity, we consider the neu- tron in an external electric field. For the proton, there are additional Born couplings to the total charge. In momentum space, such terms can be subtracted; whereas in coordinate space, these terms must be treated to all orders in the field strength. This is accomplished by the relativistic proton propagator in Eq. (11). One way to see that the Born term must be subtracted is to consider the electric dipole operator, ⃗ p$_{E}$ .
