Phys. Rev. B 72, 075322 (2005) [10 pages]Wigner crystallization in inhomogeneous one-dimensional wiresReceived 29 October 2004; revised 22 April 2005; published 8 August 2005 We explore the theory of electrons confined by one-dimensional power-law potentials. We calculate the density profile in the high-density electron gas, the low-density Wigner crystal, and the intermediate regime. We extract the momentum-space wave function of the electron at the Fermi surface, which can be measured in experiments on tunneling between parallel wires. The onset of localization leads to a dramatic broadening of the momentum-space wave function together with pronounced sharpening (in energy) of the tunneling spectrum. © 2005 The American Physical Society URL:
