Detailed Description

Program that calculates action for a one-dimensional potential in case in which exact solution is known (the logarithmic potential).

The potential is (see Eq. (8) of https://arxiv.org/abs/1412.3160)

\[ V(\phi) = \frac12 m^2 \phi^2 \left[1 - \ln \left(\frac{\phi^2}{w^2}\right) \right]. \]

Usage:

./logarithmic <m> <w>
