手征一维费米液体在强相互作用下的谱函数

K. A. Matveev

摘要:

我们研究动量分辨隧穿到一个系统的无自旋手性一维费米子,如电子在一个整数量子霍尔系统的边缘。粒子之间的相互作用引起系统光谱函数的展宽。我们开发了一种方法,使之能够获得的峰的形状在强相互作用制度的光谱函数。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。

英文摘要:

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.
