[edit] Summary

Description

Plot of the power shape of a Dark soliton. Its expression is simply:

I (τ) = tanh 2 (τ)

I made it with gnuplot using the following code:

# set the output
set samples 2000
set terminal svg
set output "Dark_soliton.svg"

# axis properties
set xrange [-12:12]
set yrange [0:1.3]
set xlabel "tau"
set ylabel "I(x)"

set key off

plot (sinh(x)/cosh(x))**2 linewidth 2

then I post-processed it with inkscape
