Ground state properties of quantum Kagome ice hardcore bosons
  We study the quantum Kagom\'e ice hardcore bosons, which corresponds to the XY limit of quantum spin ice Hamiltonian. We estimate the values of the zero-temperature thermodynamic quantities using the large-$S$ expansion. We show that our semi-classical analysis is consistent with finite temperature quantum Monte Carlo estimates.
