Objectives
1 We will construct the hydrodynamic equations for spin dynamics in large spin Fermi gases based on the extension of traditional Landau Fermi liquid theory. Special attentions will be paid to SU(N) Fermi gases. 2 We will discuss and extend the concept of contact to large spin Fermi systems. Connections of the contact to other important physical quantities (e.g., momentum tail, radio-frequency shift) in large spin Fermi gases will be established and their experimental consequences will be discussed. We will also make some efforts to discuss the implication of the correlations embodied in contact to spin dynamics.
