Query: Tunneling between two Luttinger liquids with long range interaction   The non linear charge transfer through a tunnel junction between two
Luttinger systems is studied for repulsive, finite range interaction between
electrons on the same, V_{11}, and on different,V_{12}, sides of the junction.
Features of the Coulomb blockade effect are observed if V_{12}=0. We predict a
novel interaction induced enhancement of the current if V_{12}>0. When
V_{12}=V_{11}, the current is suppressed at small bias, but the ``charging
energy'', obtained from the asymptotic behavior at high bias voltage, vanishes.
