Recently it has become apparent that coarse anisotropic lattices with
can be very useful in performing accurate Monte Carlo simulations of QCD at
low computational cost. This is especially true when modeling heavy quantum
states of QCD -- like glueballs, for example. Because of the exponential fall
off of the signal, small
gives better resolution of the correlators at
an early time step. On the other hand,
should be kept relatively large
because of critical slowing down.
Since the anisotropy of the lattice breaks the Euclidean invariance of the
continuum theory, it induces temporal
and spatial
correlation lengths which scale as

so that
.
On the other hand, the autocorrelations in Monte Carlo updates are proportional to a power of the correlation length
where theoretically n=2 for local stochastic updates and n=0 for cluster/overrelaxation updates.
In practice, different lattice operators will have very different
autocorrelation times, and we expect operators that couple strongly to
to have larger
. Unfortunately
``interesting operators'' in lattice QCD, like those for glueballs, live in the
spatial domain and scale with
which is large.
This work tries to address the issue of the scaling behavior of different gluon operators on anisotropic lattices, and their relevance to the problem of MC algorithm optimization.
