Over the last centuries, the understanding that atoms and molecules are the building blocks of life has led to the emergence of molecular physics. This field investigates chemical interactions, the role of molecules in biological systems, and astrophysical processes. To comprehend these complex mechanisms, it is essential to grasp the properties and interactions of atoms and molecules. Gas-phase samples allow for precise studies, as interactions with the environment are minimized. However, at room temperature, molecules and atoms move rapidly, making their details difficult to access. Cooling these particles slows them down, increasing measurement sensitivity by extending interaction times with probing systems like laser beams. The advent of laser cooling in the 1970s spurred significant growth in atomic and molecular physics, leading to the exploration of cold particle interactions. A key milestone in this field is Bose-Einstein Condensation (BEC), which occurs when particle wave functions overlap at low temperatures, revealing macroscopic quantum phenomena. This was first observed in 1995 and earned a Nobel Prize in 2001. Subsequent breakthroughs include Fermi degeneracy and atom lasers. While early research focused on atoms due to the challenges of cooling molecules, the complexity of molecular structures presents opportunities for studying effects absent in atoms. Consequently, cold molecules have gained prominence in mode
