NONEQUILIBRIUM CHARGE TRANSPORT AT A 1ST-ORDER PHASE-TRANSITION

We have studied penetration of a charge density disturbance cause by a moving bubble wall in relativistic plasma, using the self-consistent field approximation. We have shown that the charge density as a function of distance from the wall has a power-law tail 1/z2. We find that penetration of charge in plasma is most effective when the wall velocity is close to unity. However, for wall velocities mu less than or similar 0.7, the effective, in the integral sense, penetration length is found to be essentially equal to the static Debye radius.
