Abstract

Quantum spin ice in pyrochlore lattice exemplifies three-dimensional frustrated spin systems. In existing studies, Bose-Einstein condensation of bosonic spinons gives rise to magnetically ordered ground state. A truly liquid quantum spin superfluid state that manifests a deconfined Higgs condensate of spinons is demonstrated. This state is shown to occur in the fully antiferromagnetic case of the non-Kramers quantum spin ice with a fluctuation-induced first-order quantum phase transition from the U(1) spin liquid to the spin superfluid. The spin superfluid density jump is obtained analytically.
