Describing experimental signatures of quantum spin ice has been the focus of many theoretical efforts, as definitive experimental verification of this candidate quantum spin liquid is yet to be achieved. Gapped excitations known as visons have largely eluded those efforts. We provide a theoretical framework, which captures their dynamics and predicts new signatures in the magnetic response. We achieve this by studying the ringexchange Hamiltonian of quantum spin ice in the large-s approximation…

In this limit, the typical instanton separation along τ will be small by comparison with β, so that finite-size effects associated with finite temperature are negligible
