Coulomb drag between two strange metals

We study the Coulomb drag between two strange-metal layers using the Einstein-Maxwell-Dilaton model from holography. We show that the low-temperature dependence of the drag resistivity is rho D proportional to T4, which strongly deviates from the quadratic dependence of Fermi liquids. We also present numerical results at room temperature, using typical parameters of the cuprates, to provide an estimate of the magnitude of this effect for future experiments. We find that the drag resistivity is enhanced by the plasmons characteristic of the two-layer system.

Automated summary

This study investigates the Coulomb drag between two strange-metal layers using the Einstein-Maxwell-Dilaton model from holography. It reveals that the low-temperature dependence of the drag resistivity is proportional to T4, which deviates significantly from the quadratic dependence of Fermi liquids. Numerical results at room temperature using typical parameters of cuprates show an enhancement of drag resistivity due to the plasmons characteristic of the two-layer system.
