Possible Quantum Diffusion of Polaronic Muons in Dy${}_2$Ti${}_2$O${}_7$ Spin Ice

P. Quémerais, P. McClarty, R. Moessner

We interpret recent measurements of the zero field muon relaxation rate in the frustrated magnetic pyrochlore Dy${}_2$Ti${}_2$O${}_7$ as resulting from the quantum diffusion of muons in…
