Query: Interaction Control of Ultracold Alkaline-Earth Atoms   Ultracold alkaline-earth atoms have now been widely explored for precision
measurements and quantum simulation. Because of its unique atomic structure,
alkaline earth atoms possess great advantages for quantum simulation and
studying quantum many-body matters, such as simulating synthetic gauge field,
Kondo physics and $SU(N)$ physics. To fully explore the potential of ultracold
alkaline-earth atoms, these systems also need to be equipped with the
capability of tuning the inter-atomic interaction to the strongly interacting
regime. Recently several theoretical proposals and experimental demonstrations
have shown that both spin-independent and spin-exchanging interaction can be
tuned to resonance. In this perspective, we will review these progress and
discuss the new opportunities brought by these interaction control tools for
future quantum simulation studies with ultracold alkaline-earth atoms.
