Author(s): P. S. Alekseev, A. P. Dmitriev, I. V. Gornyi, V. Yu. Kachorovskii, B. N. Narozhny, and M. Titov The last few years have seen an explosion of interest in hydrodynamic effects in interacting electron systems in ultrapure materials, where the collective motion of charge carriers may resemble the flow of a viscous fluid. In a confined geometry, such as that provided by ultrahigh quality nanostructures, one expects the electronic fluid to exhibit Poiseuille-type flow profile. Here, the authors show that in two-component systems near charge neutrality the hydrodynamic viscous flow is strongly affected by the mutual friction and recombination between the two constituents leading to a strongly nonuniform current density and nonmonotonic magnetoresistance that happens to be negative (positive) in low (high) magnetic fields.
