Colloquium: Planckian dissipation in metals

SA Hartnoll, AP Mackenzie - Reviews of Modern Physics, 2022 - APS
The appearance of the Planckian time τ Pl= ℏ/k BT is reviewed in both conventional and
unconventional metals. A pedagogical discussion of the various different timescales …

Large- theory of critical Fermi surfaces. II. Conductivity

H Guo, AA Patel, I Esterlis, S Sachdev - Physical Review B, 2022 - APS
A Fermi surface coupled to a scalar field can be described in a 1/N expansion by choosing
the fermion-scalar Yukawa coupling to be random in the N-dimensional flavor space, but …

Fluctuation spectrum of critical Fermi surfaces

H Guo - Physical Review B, 2024 - APS
We investigate the low-energy effective theory of a Fermi surface (FS) coupled to an Ising-
nematic quantum critical point in (2+ 1) spacetime dimensions with translation symmetry. We …

Distinguishing viscous, ballistic, and diffusive current flows in anisotropic metals

M Qi, A Lucas - Physical Review B, 2021 - APS
We show that in anisotropic Fermi liquids where momentum-conserving scattering is much
faster than momentum-relaxing scattering processes, local imaging of the electric current …

-linear conductance in electron hydrodynamics

S Kryhin, Q Hong, L Levitov - arXiv preprint arXiv:2310.08556, 2023 - arxiv.org
A $ T $-linear temperature dependence of transport coefficients in metals is habitually
viewed as a signature of non-Fermi-liquid physics, whereas the the hallmark of Fermi-liquid …

Analogue viscous current flow near the onset of superconductivity

K Ganesan, A Lucas - arXiv preprint arXiv:2204.06567, 2022 - arxiv.org
Spatially resolved transport in two-dimensional quantum materials can reveal dynamics
which is invisible in conventional bulk transport measurements. We predict striking patterns …
