Query: Chiral Symmetry Restoration in Anisotropic QED(3)   We present results from a Monte Carlo simulation of non-compact lattice QED
in 3 dimensions in which an explicit anisotropy $\kappa$ between $x$ and $y$
hopping terms has been introduced into the action. Using a parameter set
corresponding to broken chiral symmetry in the isotropic limit $\kappa=1$, we
study the chiral condensate on $16^3$, $20^3$, and $24^3$ lattices as $\kappa$
is varied, and fit the data to an equation of state which incorporates
anisotropic volume corrections. The value $\kappa_c$ at which chiral symmetry
ispparently restored is strongly volume-dependent, suggesting that the
transition may be a crossover rather than a true phase transition. In addition
we present results on $16^3$ lattices for the scalar meson propagator, and for
the Landau gauge-fixed fermion propagator. The scalar mass approaches the pion
mass at large $\kappa$, consistent with chiral symmetry restoration, but the
fermion remains massive at all values of $\kappa$ studied, suggesting that
strong infra-red fluctuations persist into the chirally symmetric regime.
Implications for models of high-$T_c$ superconductivity based on anisotropic
QED$_3$ are discussed.
