Description
In this talk I will describe excitations in hexagonal boron nitride that are not visible in the optical response. In particular I will focus on electron-loss spectroscopy, and show that this technique can reveal the indirect nature of h-BN.Then I will discuss two-photon absorption as possible tool to probe dark states below the bright exciton of the h-BN.
