1.	Hofmann, Johannes, 1988, et al. (författare) Anomalously long lifetimes in two-dimensional Fermi liquids 2023 Ingår i: Physical Review B. - 2469-9969 .- 2469-9950. ; 108:12 Tidskriftsartikel (refereegranskat)abstract A precise characterization of the recently discovered crossover to hydrodynamic transport in electron liquids, and in particular of a conjectured exotic odd-parity transport regime, requires a full solution of the Fermi-liquid collision integral at all temperatures beyond state-of-the-art analytic leading-logarithmic approximations. We develop a general basis expansion of the linearized collision integral applicable at all temperatures, and employ this to determine the decay rates of Fermi surface perturbations in two-dimensional electron liquids. In particular, we provide exhaustive data on the decay rates for a new odd-parity regime, in which parity-even Fermi surface deformations decay rapidly but odd-parity modes are anomalously longlived. We find that this transport regime exists at fairly large temperatures T≲0.1TF, putting this regime within the reach of current experiments.
