Particle Simulation I: Assignment II

Analysis of molecular dynamics trajectories

In this assignment the ouput of a one-dimensional Lennard-Jones particle simulation was analysed to determine the behaviour of the system as a function of T. From these results the constant volume specific heat capacity (C_v) was calculated by graphical means and from the microcanonical fluctuation formulae. These results were then compared with those predicted by theory, leading to the discovery that while most of the results agreed well with theoretical predictions, the fluctuation approach to calculating C_v was somewhat flawed. Suggestion for possible explanations and improvements for this approach are given in the conclusion.
