Wigner crystal in snaked nanochannels
We study properties of Wigner crystal in snaked nanochannels and show that
they are characterized by conducting sliding phase at low charge densities and
insulating pinned phase emerging above a certain critical charge density. The
transition between these phases has a devil's staircase structure typical for
the Aubry transition in dynamical maps and the Frenkel-Kontorova model. We
discuss implications of this phenomenon for charge density waves in
quasi-one-dimensional organic conductors and for supercapacitors in nanopore
materials.Comment: 4 pages, 6 figs, research at http://www.quantware.ups-tlse.f
