摘要:
有限量子线中的局域态密度(LDOS)被计算为离散能量和沿线的位置的函数。通过使用数值密度矩阵重整化群(DMRG)计算和分析玻色化技术的组合,它是可能的,以获得一个很好的理解的局部谱权重沿线的基础多体激发。
英文摘要:
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.
