Abstract
with incorrect text on page 2 and page 7. On page 2, in the left-hand column, the second sentence should read as "To our knowledge, this is the first time many-body interactions are taken into account in Hamiltonian ratchets." On page 7, the second sentence of the second paragraph in the Conclusions should read as "The latter represents to our knowledge the first time strong many-body interactions have been treated exactly in Hamiltonian ratchets 57.
