Title: (Time changed) Theory for fundamental symmetry tests with tailored molecules containing heavy isotopes<br>
<br>
Abstract: Molecules naturally generate internal fields that can in principle be<br>
tailored specifically as to enhance or suppress different effects from<br>
violations of fundamental symmetries, be it nuclear spin-independent P-odd<br>
interactions and nuclear anapole moments or P,T-odd contributions<br>
like electric dipole moments and Schiff moments. Theory plays, thus, a<br>
crucial role in i) identifying suitable molecules with favourable<br>
enhancement factors, ii) discovering pathways for efficient production of<br>
target molecules with desired isotopic composition as well as iii)<br>
analysing successful experiments in terms of fundamental parameters.<br>
<br>
<br>
I will discuss in this talk the specific examples of RaF, which was<br>
predicted entirely from scratch to be a molecular candidate for direct<br>
laser-cooling [1,2] and subsequently studied in detail by<br>
laser-spectroscopy [3,4], as well as PaF^{3+} [5], which is predicted to<br>
provide outstanding opportunities to search for a pronounced Schiff moment<br>
of the 229Pa nucleus.<br>
