Hydrodynamic approach to two-dimensional electron systems

BN Narozhny - La Rivista del Nuovo Cimento, 2022 - Springer
The last few years have seen an explosion of interest in hydrodynamic effects in interacting
electron systems in ultra-pure materials. One such material, graphene, is not only an …

Transport properties in non-Fermi liquid phases of nodal-point semimetals

I Mandal, H Freire - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
In this review, we survey the current progress in computing transport properties in
semimetals which harbour non-Fermi liquid (NFL) phases. We first discuss the widely-used …

Transport properties of strongly coupled electron–phonon liquids

A Levchenko, J Schmalian - Annals of Physics, 2020 - Elsevier
In this work we consider the hydrodynamic behavior of a coupled electron–phonon fluid,
focusing on electronic transport under the conditions of strong phonon drag. This regime …

Transport in the non-Fermi liquid phase of isotropic Luttinger semimetals

I Mandal, H Freire - Physical Review B, 2021 - APS
Luttinger semimetals have quadratic band crossings at the Brillouin-zone center in three
spatial dimensions. Coulomb interactions in a model that describes these systems stabilize …

[HTML][HTML] Thermoelectric and thermal properties of the weakly disordered non-Fermi liquid phase of Luttinger semimetals

H Freire, I Mandal - Physics Letters A, 2021 - Elsevier
We compute the thermoelectric and thermal transport coefficients in the weakly disordered
non-Fermi liquid phase of the Luttinger semimetals at zero do**, where the decay rate …

Raman response and shear viscosity in the non-Fermi liquid phase of Luttinger semimetals

I Mandal, H Freire - Journal of Physics: Condensed Matter, 2022 - iopscience.iop.org
Luttinger semimetals represent materials with strong spin–orbit coupling, harboring doubly-
degenerate quadratic band touchings at the Brillouin zone center. In the presence of …

Plasmonic quantum nonlinear Hall effect in noncentrosymmetric two-dimensional materials

R Toshio, N Kawakami - Physical Review B, 2022 - APS
We investigate an interplay between quantum geometrical effects and surface plasmons
through surface plasmonic structures, based on an electron hydrodynamic theory. First we …

[HTML][HTML] Zero sound and plasmon modes for non-Fermi liquids

I Mandal - Physics Letters A, 2022 - Elsevier
We derive the quantum Boltzmann equation (QBE) by using generalized Landau-interaction
parameters, obtained through the nonequilibrium Green's function technique. This is a …

Possible Weyl-Luttinger phase transition in pyrochlore iridates revealed by Raman scattering

P Nikolić, Y Xu, T Ohtsuki, DC Elbert, S Nakatsuji… - Physical Review B, 2024 - APS
Pyrochlore iridates are thought to be a fertile ground for the realization of topologically
nontrivial and strongly correlated states of matter. Here, we observe a magnetically driven …

Shear viscosity as a probe of nodal topology

M Moore, P Surówka, V Juričić, B Roy - Physical Review B, 2020 - APS
Electronic materials can sustain a variety of unusual, but symmetry protected, touchings of
valence and conduction bands, each of which is identified by a distinct topological invariant …
