  The combined inductive and coulombic coupling of an orbitally quantized
two-dimensional electron gas to a one-dimensional charge-density wave (CDW) is
shown to give rise to an anisotropic quantum fluid in which the Hall electric
field, current and gradient of the CDW phase are all exponentially screened
from within the bulk. The characteristic penetration depth is similar to the
London penetration depth of relevance to superconductivity.
