Query: Quantum simulations of the superfluid-insulator transition for
  two-dimensional, disordered, hard-core bosons   We introduce two novel quantum Monte Carlo methods and employ them to study
the superfluid-insulator transition in a two-dimensional system of hard-core
bosons. One of the methods is appropriate for zero temperature and is based
upon Green's function Monte Carlo; the other is a finite-temperature world-line
cluster algorithm. In each case we find that the dynamical exponent is
consistent with the theoretical prediction of $z=2$ by Fisher and co-workers.
