Query: Influences of broken time-reversal symmetry on the d.c. Josephson
  effects in d-wave superconductors   In order to examine the influences of the spatial dependence of the pair
potential, the d.c. Josephson current in d-wave superconductors is calculated
using self-consistently determined pair potentials. The results show that the
suppression of the d-wave pair potential near the insulator does not have
serious effect on the properties of the Josephson current. On the other hand,
drastic changes are obtained due to the inducement of a subdominant s-wave
component, which spontaneously breaks time reversal symmetry. Especially, a
rapid enhancement of the Josephson current at low temperature predicted in
previous formulas is strongly suppressed.
