Query: Dynamics of the Ising Spin-Glass Model in a Transverse Field   We use quantum Monte Carlo methods and various analytic approximations to
solve the Ising spin-glass model in a transverse field in the disordered phase.
We focus on the behavior of the frequency dependent susceptibility of the
system above and below the critical field . We establish the existence of an
exact equivalence between this problem and the single-impurity Kondo model at
the quantum critical point. Our predictions for the long-time dynamics of the
model are in good agreement with experimental results on
$LiHo_{0.167}Y_{0.833}F_4$.
