Marginal Fermi liquid behavior at the onset of density wave order in two-dimensional metals with flat hot spots

L Debbeler, W Metzner - Physical Review B, 2024 - APS
We analyze quantum fluctuation effects at the onset of incommensurate 2 k F charge-or spin-
density-wave order in two-dimensional metals for a model in which the ordering wave vector …

Anomalous Lifetime of Quasiparticles in Fermi Liquids as a Precursor of the Density-Wave Instability

I Seydi, SH Abedinpour, R Asgari, B Tanatar - arXiv preprint arXiv …, 2024 - arxiv.org
We analytically study the inelastic lifetime of quasiparticles due to particle-particle
interactions in a three-dimensional Fermi liquid approaching a density-wave instability …
