Here, we employ a phenomenological quasiparticle model to calculate the normal state Nernst signal in the presence of stripe order. We find that Fermi pockets caused by translational symmetry breaking lead to a strongly enhanced Nernst signal with a sign depending on the modulation period of the ordered state and other details of the Fermi surface. This implies differences between antiferromagnetic and charge-only stripes We compare our findings with recent data from $$La_{1.6-x}Nd_{0.4}Sr_xCuO_4$$ and $$YBa_2Cu_3O_y$$.
