Short-range correlations and spin-mode velocities in ultrathin one-dimensional conductors

In ultrathin wires positioned on high-k dielectric substrates or nearby metallic gates electrons can form strongly correlated one-dimensional fluids already at rather high electron densities. The density-density correlation function, charge compressibility, spin susceptibility, and electron specific heat of such fluids are calculated analytically. The results are relevant for transport and thermodynamics of novel carbon nanotube field-effect transistors and semiconductor quantum wires.
