Time Domain Terahertz Spectroscopy Study of Composite Spin Excitations in a Quantum Spin Ice

ORAL

Abstract

We report the terahertz transmission spectra of the quantum spin ice material $Yb_{2}Ti_{2}O_{7}$. Several branches of magnetic absorption are observed with applied magnetic field. We compare the experimental results with classical spin wave analysis, and identify signatures of composite spin excitations.
