Query: A recursive approach to determine correlation functions in multi-baryon
  systems   We propose a recursive algorithm for the calculation of multi-baryon
correlation functions that combines the advantages of a recursive approach with
those of the recently proposed unified contraction algorithm. The independent
components of the correlators are built recursively by adding the baryons one
after the other in a given order. The list of nonzero independent components is
also constructed in a recursive manner, significantly reducing the resources
required for this step. We computed the number of operations required to
calculate the correlators up to Be^8, and observed a significant speedup
compared to other techniques. For the calculation of He^4 and Be^8 correlation
functions in the fully relativistic case O(10^8) operations are required,
whereas for non-relativistic operators this number can be reduced to e.g.
O(10^4) in the case of He^4.
