Square well lines potential

The square well lines (SWL) potential is given by Eq. 5:

${\mathrm{\Phi }}_{\mathrm{S}\mathrm{W}\mathrm{L}}(1,2)=\frac{ϵn^2}{L^2}\underset{-L/2}{\overset{L/2}{\int }}\underset{-L/2}{\overset{L/2}{\int }}[H(s_2-r(\lambda ,\mu ))-H(s_1-r(\lambda ,\mu ))]\mathrm{d}\mu \mathrm{d}\lambda$

where $H()$ is the Heaviside step distribution.
