Abstract
Hypothetical topologically nontrivial superconducting state of two-dimensional electron system is discussed in connection with the problem of pairing with large center-of-mass pair momentum under predominant repulsive screened Coulomb interaction. Direct numerical solution of the self-consistency equation exhibits two nearly degenerate order parameters which can be formally referred to and orbital symmetry. Spontaneous breaking of the time-reversal symmetry can mix these states and form fully gapped chiral superconducting state.
