非临界Luttinger结
Off-critical Luttinger Junctions
摘要：
我们研究了远离临界态的量子线的Luttinger结。与结处的非临界边界条件相对应的单体散射矩阵在一般情况下允许反束缚态和/或束缚态。他们对理论的贡献是由因果关系决定的。束缚态的存在/不存在决定了具有不等效物理性质的两个不同区域的存在。没有束缚态的散射矩阵定义了一个孤立的平衡系统。相反，束缚态驱使系统远离平衡，从而提高了结点中的非平凡输入或输出能量流。我们推导出在这两个制度和明确的形式的电磁电导张量，指出不同的影响的束缚态和反束缚态。
英文摘要：
We investigate Luttinger junctions of quantum wires away from criticality. The one-body scattering matrix, corresponding to the off-critical boundary conditions at the junction, admits in general antibound and/or bound states. Their contribution to the theory is fixed by causality. The presence/absence of bound states determines the existence of two different regimes with inequivalent physical properties. A scattering matrix without bound states defines an isolated equilibrium system. Bound states instead drive the system away from equilibrium, giving raise to non-trivial incoming or outgoing energy flows in the junction. We derive in both regimes and in explicit form the electromagnetic conductance tensor, pointing out the different impact of bound and antibound states.
