Coulomb Drag in Double Layers with Correlated Disorder
I. V. Gornyi, A. G. Yashenkin, D. V. Khveshchenko
We study the effect of correlations between impurity potentials in different layers on the Coulomb drag in a double-layer electron system. It is found that for strongly correlated…
Quantum transport of composite fermions in narrow constrictions
D. V. Khveshchenko
We elaborate on a single-mode description of the ballistic charge transport through a narrow constriction in a compressible (composite fermion) Quantum Hall liquid. In the presence…
Intrinsic temperature dependences of transport coefficients within the hot-spot model for normal state YBCO
J. Paaske, D. V. Khveshchenko
The temperature dependences of the galvanomagnetic and thermoelectric transport coefficients within a generic hot-spot model are reconsidered. Despite the recent success in explain…
Quantum point contact in a compressible Quantum Hall liquid
D. V. Khveshchenko
We consider electron transport through a quantum point contact between compressible Quantum Hall liquids and derive the contact's impedance function for both diffusive and ballisti…
Non Fermi liquid renormalization of the conductivity of fermions coupled to gauge fields
D. V. Khveshchenko, Michael Reizer
The method of the quantum kinetic equation is applied to the problem of renormalization of the conductivity of normal metals by gauge electron-electron interactions. It is shown th…
