Tunneling decay of false kinks

Understand

We consider the decay of "false kinks," that is, kinks formed in a scalar field theory with a pair of degenerate symmetry-breaking false vacua in 1+1 dimensions.

• The true vacuum is symmetric.
• A second scalar field and a peculiar potential are added in order for the kink to be classically stable.
• We find an expression for the decay rate of a false kink.
