  Majorana fermions are a fascinating medium for discovering new phases of
matter. However, the standard analytical tools are very limited in probing the
non-perturbative aspects of interacting Majoranas in more than one dimensions.
Here, we employ the holographic correspondence to determine the specific heat
of a two-dimensional interacting gapless Majorana system. To perform our
analysis we first describe the interactions in terms of a pseudo-scalar torsion
field. We then allow fluctuations in the background curvature thus identifying
our model with a $(2+1)$-dimensional Anti-de Sitter (AdS) geometry with
torsion. By employing the AdS/CFT correspondence, we show that the interacting
model is dual to a $(1+1)$-dimensional conformal field theory (CFT) with
central charge that depends on the interaction coupling. This non-perturbative
result enables us to determine the effect interactions have in the specific
heat of the system at the zero temperature limit.
