I will discuss recent work with Harald Helfgott in which we establish roughly speaking that the graph connecting n to n +/- p with p a prime dividing n is almost "locally Ramanujan". As a result we obtain improvements of results of Tao and Tao-Teravainen on logarithmic Chowla. I will discuss the main ideas in the proof and the connections with logarithmic Chowla.
