Abstract: Recently the Schur index of N=4 SYM was evaluated in closed form to all orders including exponential corrections in the large N expansion and for fixed finite N. This was achieved by identifying the matrix model which calculates the index with the partition function of a system of free fermions on a circle. The index can be enriched by the inclusion of loop operators and the case of Wilson loops is particularly easy, as it amounts to inserting extra characters into the matrix model. The Fermi-gas approach is applied here to this problem, the formalism is explored and explicit results at large N are found for the fundamental as well as a few other symmetric and antisymmetric representations.
