Defect production behind the shock wave front of an inhomogeneous quench.
The creation of defects behind the half kink in the presence of external force distributions is considered. The influence of external potentials on kink production behind the shock wave front of an inhomogeneous quench is examined. It is shown that depending on the impurity strength and orientation its interaction with the front of the decaying false vacuum, even in homogenous systems, may lead to single or even multiple defect production in the vicinity of the impurity center.
