  The thick brane scenario built on the f(T,B) teleparallel gravity theory was
considered for the study of phase transitions, internal structures, and new
classes of solutions in a model. In this theory, T denotes the torsion scalar,
and B is a boundary term. An interesting result was observed when brane
splitting occurs, i. e., internal structures in the model arise as a
consequence of the appearance of new domain walls in the theory. In fact, this
preliminary result influences the profile of the matter field (from kink to
multi-kink) so that for appropriate values of the parameters $k_{1,2}$ multiple
phase transitions are identified. To perform this analysis, the Differential
Configurational Entropy (DCE) which has the ability to predict the existence of
phase transitions through critical points was used. Furthermore, the DCE is
able to select the most stable solutions since it gives us details about the
informational content of the field settings.
