Direct observation of vortices in an electron fluid

A Aharon-Steinberg, T Völkl, A Kaplan, AK Pariari… - Nature, 2022 - nature.com
Vortices are the hallmarks of hydrodynamic flow. Strongly interacting electrons in ultrapure
conductors can display signatures of hydrodynamic behaviour, including negative non-local …

Electron hydrodynamics of two-dimensional anomalous Hall materials

EH Hasdeo, J Ekström, EG Idrisov, TL Schmidt - Physical Review B, 2021 - APS
We study two-dimensional (2D) electron systems in the hydrodynamic regime. We show that
a geometrical Berry curvature modifies the effective Navier-Stokes equation for viscous …

Shear viscosity expression for a graphene system in relaxation time approximation

CW Aung, TZ Win, G Khandal, S Ghosh - Physical Review B, 2023 - APS
We have gone through the detailed microscopic calculation of the shear viscosity of a 2-
dimensional graphene system in the relaxation time approximation–based kinetic theory …

Hydrodynamics with triangular point group

AJ Friedman, CQ Cook, A Lucas - SciPost Physics, 2023 - scipost.org
When continuous rotational invariance of a two-dimensional fluid is broken to the discrete,
dihedral subgroup $ D_6 $-the point group of an equilateral triangle-the resulting …

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 …

Nonreciprocal electron hydrodynamics under magnetic fields: applications to nonreciprocal surface magnetoplasmons

R Sano, R Toshio, N Kawakami - Physical Review B, 2021 - APS
Recent experiments have elucidated that novel nonequilibrium states inherent in the so-
called hydrodynamic regime are realized in ultrapure metals with sufficiently strong …

Graphene is neither relativistic nor non-relativistic: thermodynamics aspects

TZ Win, CW Aung, G Khandal, S Ghosh - Pramana, 2025 - Springer
Discovery of electron hydrodynamics in graphene systems has opened a new scope of
theoretical research in condensed matter physics, which was traditionally well cultivated in …

Spin-hydrodynamics of electrons in graphene and magnetization due to thermal vorticity

A Jaiswal - arxiv preprint arxiv:2409.07764, 2024 - arxiv.org
We examine the framework of relativistic spin-hydrodynamics in the context of electron
hydrodynamics in graphene. We develop a spin-hydrodynamic model for a (2+ 1) …

Wiedemann-Franz law violation domain for graphene and nonrelativistic systems

TZ Win, CW Aung, G Khandal, S Ghosh - arxiv preprint arxiv:2404.01061, 2024 - arxiv.org
Systematic and comparative research on Lorenz ratios for graphene and nonrelativistic
systems has been studied to identify their Wiedemann-Franz law violation domain. Fermi …
