Coleman-de Luccia Tunneling Wave Function

Understand

We revisit the famous Coleman-de Luccia formalism for decay of false vacuum in gravitational theory.

• Since the corresponding wave function is time-independent we argue that its instanton's interpretation as the decay rate probability is problematic.
• We instead propose that such phenomenon can better be described by the Wheeler-de Witt's wave function.
• To do so, the Hamilton-Jacobi formalism is employed in the WKB approximation.
