Abstract

Since graphene’s discovery in 2004, it has been established as one of the most important materials in recent condensed matter history. Understanding its properties and potential uses has been the subject of intense scientific research around the world. Graphene’s unique physical properties allow it to serve a wide variety of purposes, from its everyday role in the formation of graphite in pencils to its more cutting-edge scientific functions in electronics and energy storage. Gaining a better understanding of graphene’s rich quantum landscape through geometric and topological phenomena, like Berry curvature and Berry dipole, could have significant implications for both theoretical investigations and practical applications. This thesis discusses these effects by varying the hopping parameters of graphene and examining how the Berry curvature and Berry dipole change to gain insight into the altered behavior of the material. A deeper understanding of these effects is essential to advancing the fundamental concepts of condensed matter physics and, in turn, leading to innovative technological discoveries.
