abstract = {<p style="text-align: justify;">The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is the superconducting
phase for which the Cooper pairs have a non-zero total momentum, depending on the
splitting of the Fermi surface sheets for electrons with opposite spin. In infinite systems
the momentum is a continuous function of the temperature. In this paper, we have
shown how the finite size of the system, through the discretized geometry of the Fermi
surface, affects the physical properties of the FFLO state by introducing discontinuities
in the Cooper pair momentum. Our calculations in an isotropic system show that the
superconducting state with two opposite Cooper pair momenta is more stable than
state with one momentum also in nano-size systems, where finite size effects play a
crucial role.</p>},
