  We propose a scenario where the effects of dislocations, in bidimensional
Dirac materials at low energies, can be described within a Dirac field theory
by a vertex proportional to the totally antisymmetric component of the torsion
generated by such dislocations. The well-known geometrical obstruction to have
a nonzero torsion term of that kind in this two-dimensional settings is
overcome through exotic time-loops, obtained from ingeniously manipulated
particle-hole dynamics. If such torsion/dislocation is indeed present, a net
flow of particles-antiparticles (holes) can be inferred and possibly measured.
Finally, we comment on how these discoveries pave the way to a laboratory
realization on Dirac materials of Unconventional Supersymmetry, as a top-down
description of the $\pi$-electrons in backgrounds with a nonzero torsion.
