Spin-Charge Separation in Angle-Resolved Photoemission Spectra
Hidekatsu Suzuura, Naoto Nagaosa
Abstract
The implications of the angle-resolved photoemission spectroscopy (ARPES) on the issue of spin-charge separation are discussed from the viewpoint of slave-particle RVB theories. It is pointed out that the non-local phase string is essential to reproduce the two-peak structure experimentally observed in SrCuO2. The comparison between 1D and 2D cases is also made.
