The scaling theory of the transitions between plateaus of the Hall conductivity in the integer
quantum Hall effect is reviewed. In the model of two-dimensional noninteracting electrons in …

Coulomb drag is a transport phenomenon whereby long-range Coulomb interaction
between charge carriers in two closely spaced but electrically isolated conductors induces a …

The diagrammatic linear response formalism for the Coulomb drag in two-layer systems is
developed. This technique can be used to treat both elastic disorder and intralayer …

The advances in the techniques used for fabrication and lithography of semiconductors have
made it possible to study bi-layer systems made of two electronic layers separated by …

We derive an expression for the drag rate (ie, interlayer momentum transfer rate) for carriers
in two coupled two-dimensional gases to lowest nonvanishing order in the screened …

We show theoretically that the Coulomb drag rate between two parallel quasi-two-
dimensional electron gases with equal Fermi velocities is substantially enhanced by the …

On the basis of the Chalker-Coddington network model, a numerical and analytical study is
made of the statistics of point-contact conductances for systems in the integer quantum Hall …

The quantum phenomena of tunneling and interference show up not only in the microscopic
world of atoms and molecules, but also in cold materials of the real world, such as metals …

We report the experimental observation of Coulomb drag in two parallel, ballistic quantum
wires fabricated from a high-mobility 2DEG at the interface of a AlGaAs/GaAs heterostructure …

We study the transconductance for two coupled one-dimensional wires or edge states
described by Luttinger liquid models. The wires are assumed to interact over a finite …
