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…

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…
