graphene in certain regimes. One way to get around this is using the AdS/CFT-

model specic (e.g. embeddings, stabilizing magnetic

or physical quantities (e.g. temperature, charge density) that allowed for searches
in a large parameter space. This
exibility allowed us to compare the results
from our model with similar studies. However, no plasmons were found within the
model. We discuss some possible shortcomings of the model and outline future
research directions.},

AB Since its discovery in 2004, graphene has been a hot topic in research. As it is a
two-dimensional material it has many exciting and often extreme properties. It has
recently been shown to possess strongly coupled properties, implying that standard
methods such as perturbation theory fails to properly depict the behaviour of
graphene in certain regimes. One way to get around this is using the AdS/CFT-
duality discovered by Maldacena in 1997. This approach has previously been
carried out with success, predicting several properties of similar materials. One
property that has yet to be described by such models however is the existence of
plasmons.
The purpose of this thesis was therefore to investigate this issue. We built a
top-down D3-D7'-model in the same fashion as previously done by Jokela et al.
The model was then incorporated into Wolfram Mathematica for the numerical
calculations. In the model we had a number of dierent choices that were either
model specic (e.g. embeddings, stabilizing magnetic
uxes, boundary conditions)
or physical quantities (e.g. temperature, charge density) that allowed for searches
in a large parameter space. This
exibility allowed us to compare the results
from our model with similar studies. However, no plasmons were found within the
model. We discuss some possible shortcomings of the model and outline future
research directions.
