Disorder-Induced Quantum Spin Liquid in Spin Ice Pyrochlores

ORAL

Abstract

We discuss disorder in spin ice materials, and in particular in compounds with non-Kramers magnetic ions. We show that in the minimal relevant model, disorder succeeds in inducing a long-range entangled Coulombic quantum spin liquid phase. The phase diagram also contains an analog of the Mott glass state, envisioned in dirty boson systems with particle-hole symmetry. We discuss the relevance of our results to the material Pr$_2$Zr$_2$O$_7$, and how these ideas might be applied to convert a classical spin ice to a quantum one.
