Electron Hydrodynamics and Bernoulli Effect in Venturi-Shaped 2D Systems
C. A. Monari, A. D. Levin, A. S. Jaroshevich +5
The study of electron hydrodynamics provides a powerful framework for understanding transport in ultraclean conductors, yet experimental evidence has thus far been largely restrict…
Spectroscopy of Heat Transport and Violation of the Wiedemann--Franz Law in a GaAs Hydrodynamic Mesoscopic Channel
Yu. A. Pusep, M. A. T. Patricio, M. M. Glazov +5
The Wiedemann--Franz law, which determines the universality of the ratio of thermal conductivity to electrical conductivity, is studied in the hydrodynamic electron transport regim…
Viscous Electron Flow and Nonlinear Magnetotransport in 2D Channels
A. D. Levin, G. M. Gusev, A. K. Bakarov
We examine nonlinear transport in a viscous two-dimensional electron fluid within narrow GaAs channels. The differential magnetoresistance shows nonmonotonic behavior, a signature…
Interaction Induced Magnetotransport in a 2D Dirac-Heavy Hole Hybrid Band System
G. M. Gusev, A. D. Levin, V. A. Chitta +2
While electron-electron (e-e) interactions are known to influence resistivity in non-Galilean invariant two-dimensional (2D) systems, their effect on magnetotransport is not fully…
Obstacle-Induced Gurzhi Effect and Hydrodynamic Electron Flow in Two-Dimensional Systems
A. D. Levin, G. M. Gusev, V. A. Chitta +5
The viscous flow of electrons in a narrow channel requires both strong electron-electron interactions and no-slip boundary conditions. However, introducing obstacles within the liq…
