Local Density of States for Individual Energy Levels in Finite Quantum Wires
arXiv:0806.0027 · doi:10.1103/PhysRevLett.101.206401
Abstract
The local density of states (LDOS) in finite quantum wires is calculated as a function of discrete energies and position along the wire. By using a combination of numerical density matrix renormalization group (DMRG) calculations and analytical bosonization techniques it is possible to obtain a good understanding of the local spectral weights along the wire in terms of the underlying many-body excitations.
