A system of ultracold alkali (6Li, 40K) and alkaline-earth atoms (87Sr) will investigate the quantum simulation properties. Feshbach resonance (FR) is an essential tool for changing the interaction between particles by changing the magnetic field strength between the atoms. FR are of two kinds magnetic Feshbach resonance (MFR) and orbital Feshbach resonance (OFR), dealing with one band and two-band physics, respectively. In orbital Feshbach resonance, the energy difference between open and closed channels is in the range of Fermi energy or even smaller, reducing to zero or at no magnetic field. The atomic structural analysis of one valence electron in the outermost orbit for alkali atoms has widely explored the superfluidity and single-particle phenomena. The system of alkaline-earth atoms provides an excellent opportunity for the investigation of quantum simulation and quantum many-body matters such as the simulation of synthetic gauge field, Kondo physics, and SU(N) physics. This work studies spin-orbit coupled (SOC) physics in alkaline-earth (AE) atoms like 173Yb in two different electronic and nuclear hyperfine states. We discuss the interaction between particles in the hyperfine states by varying the interatomic distance. Here we will discuss short-range potential (in singlet and triplet channels at finite field strength) and long-range potential (open and closed channels for zero-field strength). We discuss the single-particle density-of-states (DOS) in the open and closed channel above superfluid phase transition temperature to study the normal-state properties of two particular nuclear hyperfine states.
