Description
In the talk we review the methods how relativistic bound
states can be calculated in quantum field theory. We build up a
renormalization group framework for solving the corresponding equations.
We demonstrate in the exactly solvable nonrelativistic QED case, how
these ideas work. Finally we show that in the symmetric phase of the NJL
model there is an attractive potential between the constituents that may
lead to formation of bound states.
