The work of our group on reproducing scenarios of high energy theoretical physics on Dirac
materials, like graphene, is illustrated. The main goal of this paper is to explain how versatile
these systems are, and how far and wide into the hep-th territory we can explore with them. I first
review why these materials lend themselves to the emergence of special relativistic-like matter and
space, with the focus on the emergence of curvature. Then the crucial role of the low dimensions
(2+1), and Weyl symmetry, towards the realization of a Unruh-kind of phenomenon (along with
other interesting scenarios, that include the BTZ black hole and de Sitter spacetime) is explained.
Comments on how far we went in the direction of experiments are offered too, followed by a
list of some fresh results: From the time-loop to spot torsion, to the generalized uncertainty
principle stemming from and underlying (lattice) length; From a model of grain-boundaries and
their relation to (A)dS and Poincaré spacetime algebras, to Unconventional Supersymmetry and
the role of the two Dirac points of graphene; and more. In the concluding remarks I briefly try
to make the case for the realization of a “CERN for analogs”, where theorists. both of the hep-th
and of the cond-mat types, sit next to experimentalists, mostly of the cond-mat type.
