Query: Fulde-Ferrel-Larkin-Ovchinnikov State due to Antisymmetric
  Spin-Orbit-Coupling in Noncentrosymmetric Superconductivity CePt$_3$Si   When the inversion symmetry is broken, the spin-orbit coupling reduces the
transition temperature of some types of spin triplet superconductivity, which
is similar to the case that magnetic field reduces the spin singlet
superconductivity due to Zeeman splitting. It is well known that
Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state of spin singlet superconductivity
is realized near the Pauli limit (or Chandrasekhar-Clogston limit) of external
magnetic field. In FFLO state the amplitude of the order parameter is not
uniform in space. In this paper we study the FFLO state in the spin triplet
superconductivity in the absence of magnetic field due to the spin-orbit
coupling. Although the FFLO state is not realized in the simple model with
spherical Fermi surface, it will be stabilized if some condition is favorable
for it. We discuss the possibility of FFLO state in CePt$_3$Si in the absence
of external magnetic field.
