Frictional magnetodrag between spatially separated two dimensional electron gases mediated by virtual phonon exchange

TL;DR

This paper investigates how virtual phonon exchange causes magnetodrag between two separate 2D electron gases, analyzing effects of magnetic field, temperature, and spacing with and without screening.

Contribution

It provides a detailed calculation of magnetodrag considering virtual phonon exchange and screening effects, advancing understanding of interlayer electron interactions.

Findings

Drag rate varies with magnetic field, temperature, and spacing.

Screening effects significantly influence the drag rate.

Virtual phonon exchange is a key mechanism in magnetodrag.

Abstract

We have studied magnetodrag between spatially separated two dimensional electron systems due to the virtual phonon exchange with and without taking into account the screening effects. The drag rate as a function of magnetic field, temperature, and interlayer spacing is calculated.
