Local Density of States for Individual Energy Levels in Finite Quantum Wires

摘要

The local density of states (LDOS) in finite quantum wires is calculated as afunction of discrete energies and position along the wire. By using acombination of numerical density matrix renormalization group (DMRG)calculations and analytical bosonization techniques it is possible to obtain agood understanding of the local spectral weights along the wire in terms of theunderlying many-body excitations.
