Title: Theory of quasiparticle interference in Kitaev quantum spin liquids

Title: Kitaev量子自旋液体中的准粒子干涉理论

Authors:Ammar Jahin, Hao Zhang, G치bor B. Hal치sz, Shi-Zeng Lin
Abstract: We study quasiparticle interference (QPI) in the Kitaev quantum spin liquid (QSL) for electrons tunneling into the QSL. The local tunneling conductance around a spin vacancy or localized vison reveals unique features associated with fractionalized Majorana fermions, chargons, and visons. In certain parameter regimes, the single-spinon density of states and momentum dispersion can both be directly extracted from the tunneling conductance. Our results suggest that QPI is a promising tool for identifying the Kitaev QSL and its fractionalized excitations.
