Recent experiments on the spin-ice material Dy2Ti2O7 suggest that the Pauling"ice entropy", characteristic of its classical Coulombic spin-liquid state, maybe lost at low temperatures [D. Pomaranski et al., Nature Phys. 9, 353 (2013)].However, despite nearly two decades of intensive study, the nature of theequilibrium ground state of spin ice remains uncertain. Here we explore howlong-range dipolar interactions D, short-range exchange interactions, andquantum fluctuations combine to determine the ground state of dipolar spin ice.We identify a new organisational principle, namely that ordered ground statesare selected from a set of "chain states" in which dipolar interactions areexponentially screened. Using both quantum and classical Monte Carlosimulation, we establish phase diagrams as a function of quantum tunneling g,and temperature T, and find that only a very small g_c << D is needed tostabilize a quantum spin-liquid ground state. We discuss the implications ofthese results for Dy2Ti2O7.
