📚 ABSTRACT:
Electrons in ferromagnetic kagome metals exhibit intriguing behavior beyond the conventional Fermi liquid model. In this study, we explore a novel approach to visualize charge fractionalization in these materials. We begin with a brief introduction to the Angle-Resolved Photoemission Spectroscopy (ARPES) technique, focusing on the micro-focused laser-based ARPES setup. Subsequently, we delve into the analysis of photoemitted electrons from the kagome metal, revealing evidence of fractionalized electrons. Other and related collaborative investigations of electrons with unique shapes and topology using ARPES will also be discussed.
