Wigner crystal vs. Friedel oscillations in the 1D Hubbard model
Stefan A. Soeffing, Michael Bortz, Imke Schneider +3
We analyze the fermion density of the one-dimensional Hubbard model using bosonization and numerical DMRG calculations. For finite systems we find a relatively sharp crossover even…

Local Density of States for Individual Energy Levels in Finite Quantum Wires
Imke Schneider, Alexander Struck, Michael Bortz +1
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…
