The so-called configurational entropy (CE) framework has proved to be an
efficient instrument to study nonlinear scalar field models featuring
solutions with spatially-localised energy, since its proposal by Gleiser
and Stamapoulos. Therefore, in this work, we apply this new physical
quantity in order to investigate the properties of degenerate Bloch
branes. We show that it is possible to construct a configurational
entropy measure in functional space from the field configurations, where
a complete set of exact solutions for the model studied displays both
double and single-kink configurations. Our study shows a rich internal
structure of the configurations, where we observe that the field
configurations undergo a quick phase transition, which is endorsed by
information entropy. Furthermore, the Bloch configurational entropy is
employed to demonstrate a high organisational degree in the structure of
the configurations of the system, stating that there is a best ordering
for the solutions. (C) 2017 The Author(s). Published by Elsevier B.V.
