Detailed Description

Program that calculates action for a one-dimensional potential in a thin-wall case, in which exact solution is known.

The potential is (see Eq. (4.5) of https://journals.aps.org/prd/pdf/10.1103/PhysRevD.15.2929)

\[ V(\phi) = \frac{\lambda}{8} (\phi^2 - a^2)^2 + \frac{\epsilon}{2 a} (\phi - a). \]

Usage:

./thin <lambda> <a> <delta>
