We present a formalism based on the functional Schr”odinger equation to
analyse time-dependent tunneling in quantum field theory at the semi-classical
level. The full problem is reduced step by step to a finite dimensional quantum
mechanical setup and solved using the WKB approximation. As an example, we
consider tunneling from a homogeneous oscillating initial state in scalar
quantum field theory.
