Read the full paper: here Link to the online version: here Collective coordinates in a many-particle system are complex Fourier components of the particle density $$n(\mathbf{x}) \equiv \sum_{j=1}^N \delta(\mathbf{x}-\mathbf{r}_j)$$, and often provide useful physical insights. However, given collective coordinates, it is desirable to infer the particle coordinates via inverse transformations. In principle, a sufficiently large … Continue Reading “Inversion Problems for Fourier Transformation of Particle Distributions” is published in Journal of Statistical Mechanics: Theory and Experiment
