Electron transport in Si/SiGe modulation-doped heterostructures using Monte Carlo simulation

F. Monsef, P. Dollfus, S. Galdin-Retailleau +2

The electron transport in the two-dimensional gas formed in tensile-strained Si1-xGex/Si/Si1-xGex heterostructures is investigated using Monte Carlo simulation. At first the electr…

Weak localization in multiterminal networks of diffusive wires

Christophe Texier, Gilles Montambaux

We study the quantum transport through networks of diffusive wires connected to reservoirs in the Landauer-Büttiker formalism. The elements of the conductance matrix are computed b…

Effect of interactions on the noise of chiral Luttinger liquid systems

B. Trauzettel, P. Roche, D. C. Glattli +1

We analyze the current noise, generated at a quantum point contact in fractional quantum Hall edge state devices, using the chiral Luttinger liquid model with an impurity and the a…

A one-channel conductor in an ohmic environment: mapping to a TLL and full counting statistics

Ines Safi, Hubert Saleur

It is shown that a one-channel mesoscopic conductor in an ohmic environment can be mapped to the problem of a backscattering impurity in a Tomonaga-Luttinger liquid (TLL). This all…

On the ballistic transport in nanometer-scaled double-gate MOSFET

J. Saint Martin, A. Bournel, P. Dollfus

The scattering effects are studied in nanometer-scaled double-gate MOSFET, using Monte Carlo simulation. The non-equilibrium transport in the channel is analyzed with the help of t…

Quantum transport through carbon nanotubes: proximity induced and intrinsic superconductivity

A. Kasumov, M. Kociak, M. Ferrier +6

We report low temperature transport measurements on suspended single walled carbon nanotubes (both individual tubes and ropes). The technique we have developed, where tubes are sol…

Microscopic Theory of the Reentrant IQHE in the First and Second Excited LLs

M. O. Goerbig, P. Lederer, C. Morais Smith

We present a microscopic theory for the recently observed reentrant integral quantum Hall effect in the n=1 and n=2 Landau levels. Our energy investigations indicate an alternating…

Mesoscopic Fluctuations in Quantum Dots in the Kondo Regime

R. K. Kaul, Denis Ullmo, Harold U. Baranger

Properties of the Kondo effect in quantum dots depend sensitively on the coupling parameters and so on the realization of the quantum dot -- the Kondo temperature itself becomes a…

Charge and currents distribution in graphs

Christophe Texier, Pascal Degiovanni

We consider graphs made of one-dimensional wires connected at vertices, and on which may live a scalar potential. We are interested in a scattering situation where such a network i…

Quantum Hall Conductivity in a Landau Type Model with a Realistic Geometry

F. Chandelier, Y. Georgelin, T. Masson +1

In this paper, we revisit some quantum mechanical aspects related to the Quantum Hall Effect. We consider a Landau type model, paying a special attention to the experimental and ge…

Environmental effects in the third moment of voltage fluctuations in a tunnel junction

B. Reulet, J. Senzier, D. E. Prober

We present the first measurements of the third moment of the voltage fluctuations in a conductor. This technique can provide new and complementary information on the electronic tra…

Scaling Approach to the Phase Diagram of Quantum Hall Systems

M. O. Goerbig, C. Morais Smith

We present a simple classification of the different liquid and solid phases of quantum Hall systems in the limit where the Coulomb interaction between the electrons is significant,…
