Chromium is a species that has a high permanent magnetic moment leading to significant dipolar interactions. By controlling the depth of the optical lattices, it is possible to study the competition between dipolar interactions, contact interactions, and transport across the superfluid\u2013Mott phase transition. Measurement of quantum correlations has led to original studies of quantum thermalization, a process in which an isolated system evolves towards equilibrium through the growth of entanglement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u00a0In order to perform more versatile and more accurate measurements, we are re\u2010building the core of the experiment, with the development of new experimental tools: high-numerical\u2010aperture imaging, in\u2010vacuum magnetic field measurements, adaptive optics, new optical lattices setup to reach 2D geometry. The Master student will participate in the build\u2010up of the trapping laser system, for which all laser sources are available. This includes MOT, repumpers, dipolar and lattice beams. They will be associated as well to the construction of imaging systems (absorption, and fluorescence). This internship could then continue as a PhD thesis. The student will interact with all team members: Lucas Lavoine (associate professor), Benjamin Pasquiou (CNRS engineer), Laurent Vernac (professor), and a post-doctorate fellow who will start working in the winter.<br><\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>References:<\/strong><\/h5>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/arxiv.org\/pdf\/2501.11402\">T.
