1. Introduction In my previous post, we saw how to use the replica method to calculate the spectral norm of the spiked GOE matrix. Besides the spectral norm, another interesting quantity of random matrices is the spectral density: the limiting empirical distribution of eigenvalues. Similarly using the replica method, we show in this post how to calculate the spectral density of random matrices. In particular, we will illustrate the method through the example of GOE... … read more »

1. Introduction In my first several posts, I will discuss about the replica method. The replica method is a nonrigorous but powerful approach that originated within the statistical physics literature. It has been widely applied in other fields, including coding theory and high dimensional statistics. I used this method several times in my research. It helped me quickly figure out the answer of numerous problems. Most physicists know the replica method better than me. Here... … read more »
