Nuclear T-violation search using octupole-deformed nuclei in a crystal

Abstract

Precision measurements with atoms and molecules can search for subtle violations of time-reversal symmetry (T) in nuclei, and thereby probe a variety of new physics models. We present a detailed scheme for a nuclear T-violation search experiment using ${}^{153}$Eu${}^{3+}$ ions doped in non-centrosymmetric sites within a Y${}_2$SiO${}_5$ crystal. The ions in this solid contain nuclei that are highly sensitive to T-violation, and avail of large atomic enhancements by being polarized within the solid. But in particular, the system and methods that we discuss here enable the use of vast numbers of nuclei trapped in crystals, while also offering a number of stringent tests to ward off systematic errors. Our approach maps out a path to probe new physics at the PeV energy scale.
