Abstract
The tunneling through a potential barrier in a Coulomb gas confined in
a quantum wire is discussed. The tunneling conductance g(T) at temper
ature T is found to be g(F) is-proportional-to exp [ln upsilon(F)/WT -
2/3r {(1+r ln upsilon(F)/WT)3/2 - 1)}], where W is the width of the w
ire, upsilon(F) is the Fermi velocity, and r (8/pi2)r(s) = 4e2/piupsil
on(F)epsilon0 is the dimensionless mean separation between electrons.
