“…Such information is especially interesting for exotic actinide species. These nuclei and their molecular compounds are of marked interest for nuclear structure and fundamental symmetry studies [2,12,[51][52][53][54][55][56][57][58][59][60][61], but until now the experimental knowledge of their molecular and nuclear properties is lacking. Our findings offer important information to understand nuclear structure and symmetry-violating effects in molecules containing the heaviest elements of the periodic table.…”

Isotope shifts of [223][224][225][226]228 Ra 19 F were measured for different vibrational levels in the electronic transition A 2 Π 1/2 ← X 2 Σ + . The observed isotope shifts demonstrate the particularly high sensitivity of radium monofluoride to nuclear size effects, offering a stringent test of models describing the electronic density within the radium nucleus. Ab initio quantum chemical calculations are in excellent agreement with experimental observations. These results highlight some of the unique opportunities that short-lived molecules could offer in nuclear structure and in fundamental symmetry studies.

“…Searches for EDMs of diamagnetic atoms in other systems have been carried out [50][51][52][53][54]; many of these are ongoing efforts with the prospect of improving measurement accuracy by orders of magnitude, such as the radium EDM search in which several upgrades are in the process of being implemented [55,56]. There are also a number of new experiments that have the potential to explore unconstrained parameter space for symmetry violating effects in the nuclear sector [45,[57][58][59][60][61][62][63], such as the CENTREX experiment that employs a cold beam of TlF molecules [64], a search particularly sensitive to the proton EDM [65,66].…”

The applications of spin-based quantum sensors to measurements probing fundamental physics are surveyed. Experimental methods and technologies developed for quantum information science have rapidly advanced in recent years, and these tools enable increasingly precise control and measurement of spin dynamics. Theories of beyond-the-Standard-Model physics predict, for example, symmetry violating electromagnetic moments aligned with particle spins, exotic spin-dependent forces, coupling of spins to ultralight bosonic dark matter fields, and changes to the local environment that affect spins. Spin-based quantum sensors can be used to search for these myriad phenomena, and offer a methodology for tests of fundamental physics that is complementary to particle colliders and large scale particle detectors. Areas of technological development that can significantly enhance the sensitivity of spin-based quantum sensors to new physics are highlighted.

“…One promising approach to finding these violations lies in studying certain pear-shaped radioactive nuclei within polar molecules (see Viewpoint: Designer Molecules for Fundamental-Symmetry Tests). Research has shown that the energy spectra of such molecules are exceptionally sensitive probes of symmetry violations [3,4]. To harness this discovery potential, researchers need to develop a better understanding of the energy spectra of these radioactive molecules.…”

Sizing up Exotic Nuclei with Radioactive MoleculesNew research shows that radioactive molecules can be used to study the variation in the shapes and sizes of exotic nuclei that are particularly sensitive to fundamental symmetry violations.By Jaideep Taggart Singh B ecause matter and antimatter show near-perfect symmetry with respect to the laws of physics as we know them, physicists expect that equal amounts of matter and antimatter were present in the early Universe. But the concordance of ever more precise astronomical and cosmological observations indicates that the visible Universe is completely dominated by matter, with hardly any antimatter anywhere. What caused the preponderance of matter?
