<b><span style="font-size:12.0pt; font-family:"Times New Roman",serif">Abstract:</span></b><span style="font-size:12.0pt; font-family:"Times New Roman",serif"> Molecules have emerged as powerful instruments for conducting precise tests of fundamental symmetries,
such as the search for the electron electric dipole moment (eEDM). However, molecules are generally difficult to trap and cool, making it challenging to perform narrow linewidth measurements with long interrogation times without a complicated laser-cooling
setup capable of repumping multiple rovibrational levels. Our approach harnesses molecular ions, which offer distinct advantages. They can be readily stored in ion traps for prolonged durations and sympathetically cooled by laser-cooled atomic ions. Notably,
atomic lutetium ions are amenable to direct laser cooling, making them ideal candidates to serve as sympathetic coolants and to form pre-cooled molecular ions. Furthermore, Lu-176 boasts one of the largest nuclear electric quadrupole moments of any long-lived
isotope, rendering it exceptionally sensitive to the CP-violating nuclear magnetic quadrupole moment (nMQM). I will describe how we can harness these properties in molecular ions containing lutetium, such as LuOH⁺, to probe new physics through the simultaneous
investigation of nMQM and eEDM.<br>
