Local Density of States in 1D Mott insulators with a Boundary

We investigate the modification of the electronic local density of states (LDOS) in 1D strongly correlated electron systems due to a boundary or impurity. We show that the impurity LDOS can be used to probe bulk properties such as spin-charge separation of the underlying state of matter. We calculate the boundary LDOS for 1D Mott insulators and charge density wave states using methods of integrable quantum field theory.
