Understanding the behavior of interacting electrons in solids or liquids is at the heart of modern quantum science and necessary for technological advances. However, the complexity of their interactions generally prevents us from coming up with an exact mathematical description of their behavior. Precisely engineered ultracold gases are emerging as a powerful tool for unraveling these challenging physical problems. In this talk, I will present recent developments at JILA on using alkaline-earth atoms (AEAs) --currently the basis of the most precise atomic clock in the world-- for the investigation of complex many-body phenomena and magnetism. I will discuss ideas to use AEAs dressed by laser fields to engineer analogs of spin-orbit coupled Hamiltonians, as well as new forms of matter with no yet known counterpart in nature. Finally, I will discuss recent ideas on how atomic collisions can realistically be used for entanglement generation in atomic clocks which are already the state-of-the-art. These investigations would open a path for the practical improvement of world-leading quantum sensors using correlated many-body fermionic states as well as new possibilities to use the new generation of atomic clocks for quantum information processing.
