Coulomb Drag in the Extreme Quantum Limit
نویسندگان
چکیده
Coulomb drag resulting from interlayer electron-electron scattering in double layer 2D electron systems in a high magnetic field has been measured. Within the lowest Landau level the observed drag resistance exceeds its zero magnetic value by factors of typically 1000. At half-filling of the lowest Landau level in each layer (n 1y2) the data suggest that our bilayer systems are much more strongly correlated than recent theoretical models based on perturbatively coupled composite fermion metals.

Coulomb Drag As a Signature of the Paired Quantum Hall State
We show that at zero temperature the Coulomb drag between two layers of Landau level filling factor ν = 1/2 is finite in the incompressible paired quantum Hall liquid limit. The temperature dependence of the Coulomb drag exhibits a minimum near the temperature where the transition between the incompressible double layer quantum Hall liquid state and the weakly coupled compressible state takes p...
متن کاملCotunneling Drag Effect in Coulomb-Coupled Quantum Dots.
In Coulomb drag, a current flowing in one conductor can induce a voltage across an adjacent conductor via the Coulomb interaction. The mechanisms yielding drag effects are not always understood, even though drag effects are sufficiently general to be seen in many low-dimensional systems. In this Letter, we observe Coulomb drag in a Coulomb-coupled double quantum dot and, through both experiment...
متن کاملCoulomb drag in quantum circuits.
We study the drag effect in a system of two electrically isolated quantum point contacts, coupled by Coulomb interactions. Drag current exhibits maxima as a function of quantum point contacts gate voltages when the latter are tuned to the transitions between quantized conductance plateaus. In the linear regime this behavior is due to enhanced electron-hole asymmetry near an opening of a new con...
متن کاملCoulomb drag in graphene near the Dirac point.
We study Coulomb drag in graphene near the Dirac point, focusing on the regime of interaction-dominated transport. We establish a novel, graphene-specific mechanism of Coulomb drag based on fast interlayer thermalization, inaccessible by standard perturbative approaches. Using the quantum kinetic equation framework, we derive a hydrodynamic description of transport in double-layer graphene in t...
متن کاملCorrelated Coulomb Drag in Capacitively Coupled Quantum-Dot Structures.
We study theoretically Coulomb drag in capacitively coupled quantum dots (CQDs)-a bias-driven dot coupled to an unbiased dot where transport is due to Coulomb mediated energy transfer drag. To this end, we introduce a master-equation approach that accounts for higher-order tunneling (cotunneling) processes as well as energy-dependent lead couplings, and identify a mesoscopic Coulomb drag mechan...
