Carbon Nanotubes as Cooper Pair Beam Splitters (2009)
Herrmann, L. G., Portier, F., Roche, P., Yeyati, A. Levy, Kontos, T., Strunk, C.
We report on conductance measurements in carbon nanotube based double quantum dots connected to two normal electrodes and a central superconducting finger. By operating our devices as beam splitters,...
Tuning decoherence with a voltage probe (2009)
Roulleau, P., Portier, F., Roche, P., Cavanna, A., Faini, G., Gennser, U., ...
We present an experiment where we tune the decoherence in a quantum interferometer using one of the simplest object available in the physic of quantum conductors : an ohmic contact. For that purpose,...

Noise dephasing in the edge states of the Integer Quantum Hall regime (2008)
Roulleau, P., Portier, F., Roche, P., Cavanna, A., Faini, G., Gennser, U., ...
An electronic Mach Zehnder interferometer is used in the integer quantum hall regime at filling factor 2, to study the dephasing of the interferences. This is found to be induced by the electrical...
Direct measurement of the coherence length of edge states in the Integer Quantum Hall Regime (2007)
Roulleau, P., Portier, F., Roche, P., Cavanna, A., Faini, G., Gennser, U., ...
We have determined the finite temperature coherence length of edge states in the Integer Quantum Hall Effect (IQHE) regime. This was realized by measuring the visibility of electronic Mach-Zehnder...
Finite bias visibility of the electronic Mach-Zehnder interferometer (2007)
Roulleau, Preden, Portier, F., Glattli, D. C., Roche, P., Cavanna, A., Gaini, G., ...
We present an original statistical method to measure the visibility of interferences in an electronic Mach-Zehnder interferometer in the presence of low frequency fluctuations. The visibility...

Experiments on potential drops in the low temperature vortex solid phase of monocrystalline platelets of superconducting $\mathrm{Bi_2Sr_2CaCu_2O_ 8}$ (BSCCO) subjected to currents driven either...
Slow relaxation of low-temperature vortex phases in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8}$ (2006)
Portier, F., Kriza, G., Sas, B., Kiss, L.F., Pethes, I., Vad, K., ...
Nonlinear transport in the low temperature vortex glass state of single crystal Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8}$ has been investigated over long times (up to two weeks) with fast current pulses...

Experiments on potential differences in the low-temperature vortex solid phase of monocrystalline platelets of superconducting Bi(2)Sr(2)CaCu(2)O(8) (BSCCO) subjected to currents driven either...
Slow relaxation of low temperature vortex phases in Bi_{2}Sr_{2}CaCu_{2}O_{8} (2001)
Portier, F., Kriza, G., Sas, B., Kiss, L. F., Pethes, I., Vad, K., ...
Nonlinear transport in the low temperature vortex glass state of single crystal Bi_{2}Sr_{2}CaCu_{2}O_{8} has been investigated over long times (up to two weeks) with fast current pulses driven along...
Prices paid for Italian pictures in the Stuart Age (1996)
Early collectors of Italian paintings were able to buy pictures quite cheaply, direct from the Italian market. When growing competition from enthusiastic purchasers forced prices up, it remained...
Verin, E, Tardif, C, Portier, F, Similowski, T, Pasquis, P, Muir, J
Background: A study was undertaken to examine the expiratory flow response to a negative pressure (NEP) applied at the airway in patients with no abnormalities of the intrathoracic airway but...

Economic Integration, Asymmetries and the Desirability of a Monetary Union.
Carre, M, Levasseur, S, Portier, F
Symmetry of shocks across countries is often considered as a necessary condition for a monetary union. We show that the measure of shocks symmetry does not reveal a deep parameter, and depends on...
