  Non-relativistic conformal field theory describes many-body physics at
unitarity. The correlation functions of the system are fixed by the requirement
of conformal invariance. In this article, we discuss the correlation functions
of scalar operators in non-relativistic conformal field theories in momentum
space. We discuss the solution of conformal Ward identities and express 2,3,
and 4-point functions as a function of energy and momentum. We also express the
3- and 4-point functions in the momentum space as the one-loop and three-loop
Feynman diagram computations, respectively.
