Query: Binding energy of a Cooper pairs with non-zero center of mass momentum
  in d-wave superconductors   The binding energy of Cooper pairs has been calculated for the case of d-wave
symmetry of the superconducting gap in layered cuprate superconductors. We
assume that Cooper pairs are formed by the short range potential and then
derive the binding energy in the form Delta_kq = \Delta_x(q)cos(k_xa) +
\Delta_y(q)cos(k_ya) + \Omega_x(q)sin(k_xa) + \Omega_y(q)sin(k_ya), where q is
a total momentum of the pair. Numerical solutions of the self-consistent system
of the integral equations for quantities \Delta_x(q), \Delta_y(q) and
\Omega_x(q), \Omega_y(q) along different lines in q_x, q_y plane have been
obtained. Anisotropy of the depairing total momentum (or depairing current) has
been calculated.
