This phenomenon is called Anderson localization after Phillip Anderson who first predicted it in 1958. Since then, Anderson localization has remained a vibrant topic of research due to new experimental methods of probing localized states, an increase in computational power, and its accurate phenomenological representation of many physical systems. To date, a large amount of effort has been dedicated to the study of uncorrelated, or short-range correlated, disorder distributions. However, more recent efforts on long-range correlated disorder distributions have yielded richer results, challenging the foundations of Anderson localization theory. In this document, we focus on characterizing the naturally occurring ~ 1/<i>r</i> correlation, and the phenomenologically rich ~ 1/<i>k</i> correlation in one-dimensional systems. We will discuss several important numerical and analytical methods for determining a localization-delocalization transition along with the localized phase itself.
