The signature of superfluidity in bosonic systems is a sound wave-likespectrum of the single particle excitations which in the case of stronginteractions is roughly temperature independent. In fermionic systems, wherefermion pairing arises as a resonance phenomenon between free fermions andpaired fermionic states (examples are: the atomic gases of lithium or potassiumcontrolled by a Feshbach resonance, polaronic systems in the intermediarycoupling regime, d-wave hole pairing in the strongly correlated Hubbardsystem), remnants of such superfluid characteristics are expected to be visiblein the normal state. The single particle excitations maintain there a soundwave like structure for wave vectors above a certain q_{min}(T) where theypractically coincide there with the spectrum of the superfluid phase forT<T_{c}. Upon approaching the transition from above this region in q-spaceextends down to small momenta, except for a narrow region around q=0 where suchmodes change into damped free particleComment: 5 pages, 3 figures; to appear in Phys Rev
