Description
In the presence of a constant electric field the vacuum becomes
unstable due to Schwinger pair creation. One way to avoid this
instability is to use Dirichlet boundary conditions. In this
case the chiral condensate vanishes on the walls and it is important
to know how quickly it gets restored to its bulk value. A
sigma-model calculation predicts that the region where the
condensate differs significantly from its bulk value is rather thick.
We show by direct calculation that this region is much thinner
than estimated.
