Abstract
Bloch oscillations of fermionic atoms in optical lattices for the BCS-Bose Einstein Condensation (BEC) crossover regime was studied. The amplitude of the oscillations decreased when the crossover was scanned, due to the shrinking of the bandwidth. The change from the normal to the superfluid-state description led to a drastic change in the amplitude. Bloch oscillations was used for exploring pairing correlations since any localization in space led to broadening in momentum which suppresses the amplitiude in the same way as band filling in the noninteracting gas.
