... Large Deviations for Random Graphs Abstract: In this joint work with Sourav Chatterjee, we consider a random graph with n vertices, with probability p for any given edge to be present. We consider the case when p is fixed and n gets large. Asymptotically the expected number of edges is ~1/2 n2 and t ...

PH302 Introduction to Statistical Mechanics
... Statistical mechanics is branch of physics that deals with understand collective response from the single particle behavior. This course explains how the statistical approach is effective in predicting the thermodynamics of system from the constituent particles. Methods of statistical mechanics are ...
