Abstract
Scanning tunneling spectroscopy measures how a single electron with
definite energy propagates between a sample surface and the tip of a
scanning tunneling microscope. In the simplest description, the
differential conductance measured is interpreted as the local density of
states of the sample at the tip position. This picture, however, is
insufficient in some cases, since especially smaller molecules weakly
coupled with the substrate tend to have strong Coulomb interactions when
an electron is inserted or removed at the molecule. We present
theoretical approaches to go from the non-interacting and
single-particle picture to the correlated many-body regime. The
methodology is used to understand recent experiments on finite armchair
graphene nanoribbons and phthalocyanines. We also theoretically discuss
the strongly-correlated model system of fractional quantum Hall
droplets.
