A.

Abstract

We report experimental data and theoretical analysis of Coulomb drag between two closely positioned graphene monolayers in a weak magnetic field. Close enough to the neutrality point, the coexistence of electrons and holes in each layer leads to a dramatic increase of the drag resistivity. Away from charge neutrality, we observe nonzero Hall drag. The observed phenomena are explained by decoupling of electric and quasiparticle currents which are orthogonal at charge neutrality. The sign of magnetodrag depends on the energy relaxation rate and geometry of the sample.

58. Mesoscopic Fluctuations of the Coulomb Drag at nu = 1/2

Abstract

We consider mesoscopic fluctuations of Coulomb drag transresistivity between two layers at a Landau level filling factor $\nu=1/2$ each. We find that at low temperature sample to sample fluctuations exceed both the ensemble average and the corresponding fluctuations at B=0. At the experimentally relevant temperatures, the variance of the transresistivity is proportional to $T^{-1/2}$. We find the dependence of this variance on density and magnetic field to reflect the attachment of two flux quanta to each electron., Comment: 4 pages, 1 eps figure

62. Two-dimentional electron gas near full polarisation.

Author

Zala, G., Narozhny, B. N., Aleiner, I. L., Falko, Vladimir I., Zala, G., Narozhny, B. N., Aleiner, I. L., and Falko, Vladimir I.

Abstract

We establish the consistency of the Fermi liquid description and find a relation between the Fermi liquid constants for a two-dimensional electron system near the point of full polarization due to a parallel magnetic field H. Our results enable us to predict connections between different thermodynamic properties of the system. In particular, we find that near the point of full polarization Hc, the thermodynamic compressibility of the system experiences a jump with a subleading (Hc-H)1/2 dependence on the magnetic field. Also, the magnetization has a cusp with dependence of the type (H-Hc)+(Hc-H)3/2 at H
