Local density of states of 1D Mott insulators and CDW states with a boundary (2008)
Schuricht, Dirk, Essler, Fabian H. L., Jaefari, Akbar, Fradkin, Eduardo
We determine the local density of states (LDOS) of one-dimensional incommensurate charge density wave (CDW) states in the presence of a strong impurity potential, which is modeled by a boundary. We...
