Spinon Confinement and Longitudinal Interchain modes in Yb2Pt2Pb

DOI

The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with large orbital angular momentum. We have previously shown using OSIRIS that in a magnetic field, the low energy magnetic excitations - quasiparticles called spinons - become confined in low energy bound states and gain coherence between the 1D chains in the magnetically ordered state. There phenomena are condensed matter physics analogues to the quantum chromodynamics that governs the behavior of quarks and the Higgs boson, respectively. We propose to study the development of these phenomena in the vicinity of the phase transition that signals their onset at modest applied magnetic fields of around 0.5 T.
