<p style="margin:0in;margin-bottom:.0001pt;mso-add-space:auto"><span style="font-size:11.0pt;font-family:"Georgia","serif";color:black">Abstract:
</span><span style="font-size:11.0pt;font-family:"Georgia","serif";color:black">Graphene, a 2 dimensional hexagonal net of p-pi bonded carbon atoms has received an enormous theoretical and experimental attention in the past years. I will sketch how complexity
emerges from simplicity, in this mono-atomic 2-dimensional solid. Low energy electrons in graphene behave like 2 + 1 dimensional massless chiral Dirac particles. This underlies a variety of relativistic type phenomena that have been theoretically predicted:
i) Klein tunnelling, ii) Zitterbewegung, iii) Lorenz boost, iv) Lorenz contraction, v) time dilation, vi) Majarona zero mode vii) parity anomaly and so on. There are also a variety of exciting possibilities: antilocalization, universal optical absorption,
high-Tc magnetism, high-Tc chiral superconductivity in doped graphene. A pedagogic review, including some of our own work, will be presented.
