Magneto-Coulomb Drag and Hall Drag in Double-Layer Dirac Systems

Wang-Kong Tse, B. Y. K. Hu, J. N. Hong +1

We develop a theory of Coulomb drag due to momentum transfer between graphene layers in a strong magnetic field. The theory is intended to apply in systems with disorder that is we…

Theory of Coulomb Drag in Spatially Inhomogeneous Materials

Derek Y. H. Ho, Indra Yudhistira, Ben Yu-Kuang Hu +1

Coulomb drag between parallel two-dimensional electronic layers is an excellent tool for the study of electron-electron interactions. In actual experiments, the layers display spat…

Plasma Wave Instabilities in Non-Equilibrium Graphene

Chinta M. Aryal, Ben Yu-Kuang Hu, Antti-Pekka Jauho

We study two-stream instabilities in a non-equilibrium system in which a stream of electrons is injected into doped graphene. As with equivalent non-equilibrium parabolic band syst…

Density of states of disordered graphene

Ben Yu-Kuang Hu, E. H. Hwang, S. Das Sarma

We calculate the average single particle density of states in graphene with disorder due to impurity potentials. For unscreened short-ranged impurities, we use the non-self-consist…

Many-body exchange-correlation effects in graphene

E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma

We calculate, within the leading-order dynamical-screening approximation, the electron self-energy and spectral function at zero temperature for extrinsic (or gated/doped) graphene…

Coulomb Drag in Graphene

Wang-Kong Tse, Ben Yu-Kuang Hu, S. Das Sarma

We study the Coulomb drag between two single graphene sheets in intrinsic and extrinsic graphene systems with no interlayer tunneling. The general expression for the nonlinear susc…

Density dependent exchange contribution to in extrinsic graphene

E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma

We calculate in extrinsic graphene as a function of carrier density at zero temperature by obtaining the electronic self-energy within the Hartree-Fock a…

Inelastic carrier lifetime in graphene

E. H. Hwang, Ben Yu-Kuang Hu, S. Das Sarma

We consider hot carrier inelastic scattering due to electron--electron interactions in graphene, as functions of carrier energy and density. We calculate the imaginary part of the…

Infrared probe of the anomalous magnetotransport of highly oriented pyrolytic graphite in the extreme quantum limit

Z. Q. Li, S. -W. Tsai, W. J. Padilla +4

We present a systematic investigation of the magnetoreflectance of highly oriented pyrolytic graphite in magnetic field B up to 18 T . From these measurements, we report the determ…

Sign-reversal of drag in bilayer systems with in-plane periodic potential modulation

Audrius Alkauskas, Karsten Flensberg, Ben Yu-Kuang Hu +1

We develop a theory for describing frictional drag in bilayer systems with in-plane periodic potential modulations, and use it to investigate the drag between bilayer systems in wh…

Prospecting for the superfluid transition in electron-hole coupled quantum wells using Coulomb drag

Ben Yu-Kuang Hu

I investigate the possibility of using Coulomb drag to detect a precursor of the predicted (but as yet not definitively observed) superfluid transition in electron-hole coupled qua…

Theory of Transmission through disordered superlattices

Andreas Wacker, Ben Yu-Kuang Hu

We derive a theory for transmission through disordered finite superlattices in which the interface roughness scattering is treated by disorder averaging. This procedure permits eff…
