Abstract

To provide a practitioner's introduction to the study of the nuclear pasta, this article presents a brief review of the evolution of the methods used to study nucleon dynamics. This is followed with a more complete description of the extension of classical molecular dynamics (CMD) to infinite systems. The different techniques used to characterize the nuclear structure, such as cluster recognition algorithms, radial correlation functions and the Minkowski functionals are presented. We reach full functionality of the extended CMD when the Coulomb interaction is introduced through two common methodologies and its effect on the structure is presented. We close the article with some final remarks.
