Query: Intrinsic Josephson effect and nonequilibrium soliton structures in
  two-gap superconductors   We predict a new dynamic state in current-carrying superconductors with
multicomponent order parameter. If the current density J exceeds a critical
value J_t, an interband breakdown caused by charge imbalance of nonequilibrium
quasiparticles occurs. For J > J_t, the electric field penetrating from current
leads gives rise to various static and dynamic soliton phase textures, and
voltage oscillations similar to the nonstationary Josephson effect. We propose
experiments to observe these effects which would probe the multicomponent
nature of the superconducting order parameter.
