Description
Searches for violation of fundamental symmetries are among the most sensitive probes of physics of and beyond the Standard Model. Currently, precision measurements of parity P and time reversal T invariance through electric dipole moments (EDMs) in atoms and molecules are a powerful tool to probe physics at high energies, for some parameters even beyond the energy tested at high-energy colliders.
In this talk I will present two recent developments related to symmetry-violating observables in nuclei. First, I will discuss nuclear-structure calculations relevant for connecting EDM measurements in paramagnetic molecules to the proton and neutron EDMs. Second, I will introduce an extension of the in-medium similarity renormalization group (IMSRG) that enables the consistent treatment of parity-violating observables by generalizing the SRG flow equations to evolve parity-violating operators. Results obtained with this method are benchmarked against no-core shell-model calculations in light nuclei.
