We study momentum-resolved tunneling into a system of spinless chiral one-dimensional fermions, such as electrons at the edge of an integer quantum Hall system. Interactions between particles give rise to broadening of the spectral function of the system. We develop an approach that enables one to obtain the shape of the peak in the spectral function in the regime of strong interaction. We apply our technique to the special cases of short-range and Coulomb interactions.
我们研究了动量分辨隧穿进入无自旋手性一维费米子系统的情况，例如整数量子霍尔系统边缘的电子。粒子间的相互作用导致了系统谱函数的展宽。我们开发了一种方法，能够在强相互作用 regime 下获得谱函数中峰值的形状。我们将我们的技术应用于短程和库仑相互作用的特殊情况。
