Offer Description

Radioactive molecules have recently emerged as precision probes for anomalous electromagnetic moments, offering unprecedented sensitivity to parity and time-reversal violation. Despite their potential, the experimental techniques are still in early stages and often rely on advanced atomic, molecular, and optical physics technology at accelerator labs like Ganil in Caen and Triumf in Vancouver, where radionuclides are produced.

A collaboration between CNRS and the University of British Columbia (UBC) aims to advance this field, utilizing the supersonic gas jet at Ganil for nuclear moment studies via laser spectroscopy, and exploring radioactive molecules with heavy francium at Triumf. The joint PhD fellowship program facilitates knowledge exchange and enhances experimental techniques for forming cold radioactive molecules, strengthening the CNRS international research lab at Triumf.

The Irène Joliot-Curie laboratory (IJCLab), managed by CNRS, the University of Paris-Saclay, and the University of Paris, is located on the Orsay campus. It hosts over 500 staff members and conducts research in nuclear physics, high-energy physics, cosmology, and related fields. The candidate will work in the Spectroscopy-Decay-Fission group, focusing on nuclear structure experiments worldwide.

Research on fundamental symmetry violations involves detecting electric dipole, magnetic quadrupole, or Schiff moments in atoms and molecules, with heavy nuclei and actinides offering enhanced sensitivity. While atomic experiments have advanced, molecular studies remain limited. The collaboration aims to produce and study cold molecules at Ganil and Triumf, particularly focusing on molecules like LaO, LaOH, AcO, and AcOH for symmetry violation measurements.

The candidate will participate in experiments at Ganil and Triumf, analyze data, collaborate with theoreticians, and present findings. Requirements include a degree in physics or engineering, proficiency in English, and skills such as critical thinking, organization, independence, and creativity. Application should include a motivation letter, CV, and optionally recommendation letters. The candidate will enroll in the doctoral school of Paris-Saclay. Note that employment is subject to approval by the Haut Fonctionnaire Securité & Défense, which may cause delays.
