2025 Internship Projects (complete)

1. Laser Spectroscopy for New Physics (Fundamental Symmetries)

Title: Precision laser spectroscopy of ThO molecules for testing fundamental symmetries.

Advisor: X. Wu

Topic: Precision Spectroscopy, Experimental Development

Summary: Develop the laser and optics system along with the vacuum/cryogenic system to produce and measure cold Thorium Monoxide (ThO) molecules. This work aims to place stringent constraints on time-reversal violating new physics (like the electron electric dipole moment)

2. Centrifuge for Symmetry Tests (Precision Metrology)

Title: Centrifuge decelerator of radioactive molecules & atoms for fundamental symmetry tests.

Advisor: X. Wu

Topic: Experimental atomic/molecular physics and instrumentation

Summary: Develop a unique method to decelerate radioactive atoms and molecules to the ultracold regime using centrifugal force. The project involves building a spinning magnetic guide and an electromagnetic trap. This opens the door for precision spectroscopy on superheavy species (like Thorium containing molecules) - Report

AWARDED: Amin SAKKALI, University of Strasbourg

Project Report: Centrifuge Decelerator/ Summary of Accomplishment

This experimental development project successfully advanced a unique method for preparing radioactive atoms and molecules in the ultracold regime. This is a critical step in precision metrology as it enables the control and detection of particles at the single-quantum-state level. The core success was the development of the foundational elements for a centrifuge decelerator designed to bring highly unstable species to a near standstill for subsequent analysis.

3. Nucleon Distribution Reconstruction  

Title: Reconstructing nucleon distributions in nuclei

Advisor: P.Gueye

Topic: Experimental nuclear physics and instrumentation

Summary: Reconstruct the neutron distribution in various stable and rare isotopes. This is achieved by combining high-precision electron scattering data (charge distribution) with new matter radius data acquired by the MoNA Collaboration. The student will also participate in the experimental setup installation. - Report

AWARDED: Johanis BARAILLE, University of Bordeaux

Project Report: Nucleon Distribution Reconstruction /Summary of Accomplishment

This project successfully determined the neutron distribution in various stable and rare isotopes by combining two precise experimental techniques. This achievement is crucial for enhancing our understanding of nuclear interactions within the nucleus.

4. Neutron Dripline Phenomena (MoNA Collaboration: Dripline Study)

Title: Study of phenomena arising at the neutron dripline

Advisor: A. Revel

Topic: Experimental nuclear physics and instrumentation

Summary: Focus on the first MoNA collaboration experimental campaign in the FRIB Era in 2025. The project involves participating in the assembly and testing of the experimental setup, detector calibrations, developing analysis codes, and performing simulations to investigate phenomena in nuclei beyond the dripline. - Report

AWARDED: Nathan ROUSSEAUX, University of Caen Normandy

Project Report: Neutron Dripline Phenomena / Summary of Accomplishment

This project successfully supported the MoNA Collaboration's first experimental campaign in the FRIB Era (2025). The initiative was crucial for preparing the necessary instrumentation and analysis tools required to investigate fundamental phenomena in nuclei at and beyond the limit of existence (dripline), specifically focusing on the evolution of nuclear structure and the mechanism of neutron halo formation in weakly bound nuclei. 

5. Nuclear Level Density Modeling

Title: Quantum chaos and nuclear level density

Advisor: Vladimir Zelevinsky

Topic: Nuclear Theory

Summary: A theoretical project seeking to obtain a more realistic nuclear level density for heavier nuclei by assuming quantum chaos. The research addresses the computational problem of applying known methods from light nuclei to heavier cases where shell-model diagonalization is too complex.
