Hydrodynamic Anomalous Hall Effect in a Two-Dimensional Dirac Fluid
The study investigates how electron-electron collisions in a two-dimensional massive Dirac Fermi liquid cause coordinate shifts that modify transport coefficients, like the anomalous Hall effect. The analysis shows these collisional corrections are comparable to thermal effects and retain information about momentum relaxation even when disorder is zero, leading to a finite hydrodynamic Hall conductivity.
