  We analyze the dynamics of a condensate of ultra-cold atomic fermions
following an abrupt change of the pairing strength. At long times, the system
goes to a non-stationary steady state, which we determine exactly. The
superfluid order parameter asymptotes to a constant value. We show that the
order parameter vanishes when the pairing strength is decreased below a certain
critical value. In this case, the steady state of the system combines
properties of normal and superfluid states - the gap and the condensate
fraction vanish, while the superfluid density is nonzero.
