Cdw instability
Webvector q would lead to the CDW/PLD instability. The phase transition would be then preceded by the softening of a phonon mode, until it ‘freezes’ at T CDW, giving rise to the PLD with the same (or similar) wave vector q. Appearance of such a divergence in the static susceptibility we will call nesting. In the simplest scenario, such a sharp ... WebApr 4, 2024 · CDW instability. Then, in SectionIII, we perform the mean field analysis of the CDW orders. In SectionIV, we con-sider fluctuations of the CDW order parameters and present a GL free energy by incorporating the vortex configurations by means of dual fields. In SectionV, we consider a simpli-fied case, where only two CDW orders …
