• Functional renormalisation group
• Few-nucleon problem
• Deuteron-deuteron scattering lengths

A functional renormalisation group is applied to the few-nucleon problem. We have considered the average effective action with exact SU(4) symmetry and derived the flow equations which have been used to calculate the deuteron-deuteron scattering lengths in the singlet and quintet spin-isospin channels.
