A Large- Study of Quantum Kagome Ice
arXiv:1512.03930 · doi:10.1103/PhysRevB.93.144402
Abstract
We present a large- study of a quantum spin ice Hamiltonian, introduced by Huang, et al., [PRL 112, 167203 (2014)], on the kagome lattice. This model involves a competition between the frustrating Ising term of classical kagome ice, a Zeeman magnetic field ,and a nearest-neighbor transverse spin-flip term . Recent Quantum Monte Carlo (QMC) simulations by Carrasquilla, et al., [Nature Communications, 6, 7421, (2015)], uncovered lobes of a disordered phase for large Ising interaction and -- a putative quantum spin liquid phase. Here, we examine the nature of this model using large- expansion. We show that the ground state properties generally have the same trends with those observed in QMC simulations. In particular, the large- ground state phase diagram captures the existence of the disordered lobes.
