Finite doping of a one-dimensional charge density wave: Solitons vs Luttinger liquid charge density

Luttinger liquid versus charge density wave behaviour in the one-dimensional spinless fermion Holstein model

We discuss the nature of the different ground states of the half-filled Holstein model of spinless fermions in 1D. In the metallic regime we determine the renormalised effective coupling constant and the velocity of the charge excitations by a density-matrix renormalisation group (DMRG) finite-size scaling approach. At low (high) phonon frequencies the Luttinger liquid is characterised by an at...

One-dimensional conduction in charge-density-wave nanowires.

We report a systematic study of the transport properties of coupled one-dimensional metallic chains as a function of the number of parallel chains. When the number of parallel chains is less than 2000, the transport properties show power-law behavior on temperature and voltage, characteristic for one-dimensional systems.

The two dimensional electron solid charge density wave

A brief presentation of the physics and physical realisations of classical and quantum 2 dimensional electron solids is followed by a tourist guide to some of the experiments.

1/f noise in a one-dimensional charge density wave system

– The current noise in a classical one-dimensional charge density wave system is studied in the weak pinning regime by solving the overdamped equation of motion numerically. At low temperatures and just above the zero-temperature depinning threshold, the power spectrum of the current noise S(f) was found to scale with frequency f as S(f) ∼ f−γ , where γ ≈ 1, suggesting the existence of flicker ...
