\section{Readings} \section{Readings and Notes}  Notes to myself about various things to read.    \begin{itemize}  \item Bertin 2009 \url{http://perso.ens-lyon.fr/eric.bertin/lecture_notes2009.pdf}  \item \cite{http://adsabs.harvard.edu/abs/2009arXiv0901.1271K}  \item Kurchan 1998 Fluctuation Theorem  \end{itemize}     Miscellaneous stuff.   \begin{itemize}   \item Renormalisation group good for things with structure, where correlations between sites are important. Could be good for CLUSTERING investigation, especially if I can write down a Hamiltonian for the whole system composed of other particles (will certainly have to simplify this a lot!).  \end{itemize}
