Abstract : A theoretical study of the possibility of finite momentum pairing in one- and two-dimensional superconductors was carried out. When the effects of zero momentum pairing, finite momentum pairing, and a charge density wave were simultaneously considered for a one-dimensional system, it was found that the relative phases of the complex gap parameters for each of the three types of order were important. The resulting energy gap was obtained, and the nature of the ground state was examined and found to depend on the values of the effective interaction coupling constants. For the two-dimensional system, it was shown that analogous to previously known results in one dimension, the binding energy of electron pairs, as a function of momentum, has a relative maximum at momentum greater than twice the Fermi momentum.
