Engineering non-Abelian topological memories from Abelian lattice models (2009)
Wootton, James R., Lahtinen, Ville, Doucot, Benoit, Pachos, Jiannis K.
We propose a novel fault-tolerant scheme for quantum computation based on the topological phase of a spin lattice model. Abelian anyons are used to simulate non-Abelian properties relevant to...
Finite frequency noise of a superconductor/ferromagnet quantum point contact (2008)
Cottet, Audrey, Doucot, Benoit, Belzig, Wolfgang
We have calculated the finite-frequency current noise of a superconductor-ferromagnet quantum point contact (SF QPC). This signal is qualitatively affected by the spin-dependence of interfacial phase...
Superconducting Nanocircuits for Topologically Protected Qubits (2008)
Gladchenko, Sergey, Olaya, David, Dupont-Ferrier, Eva, Doucot, Benoit, Ioffe, Lev B., Gershenson, Michael E.
For successful realization of a quantum computer, its building blocks (qubits) should be simultaneously scalable and sufficiently protected from environmental noise. Recently, a novel approach to the...
Voltage-Current curves for small Josephson junction arrays (2007)
We compute the current voltage characteristic of a chain of identical Josephson circuits characterized by a large ratio of Josephson to charging energy that are envisioned as the implementation of...
Mesoscopic Full Counting Statistics and Exclusion models (2003)
Roche, Philippe-E., Derrida, Bernard, Doucot, Benoit
We calculate the distribution of current fluctuations in two simple exclusion models. Although these models are classical, we recover even for small systems such as a simple or a double barrier, the...
Une invitation à la supraconductivité. (2001)
L'esprit de ce cours a été d'aborder la supraconductivité à la fois pour elle-même (avec comme intention de mettre au premier plan un effet quantique "macroscopique" comme l'effet Josephson), et...

Effect of three-particle correlations in low dimensional Hubbard models (1993)
A simple approximation which captures some non-perturbative aspects of the one electron Green function of strongly interacting Fermion systems is developed. It provides a way to go one step beyond...
Instabilities of an elastic chain in a random potential (1993)
Jensen, Henrik, Brechet, Yves, Doucot, Benoit
We investigate a one dimensional elastic system in a random potential. The response of the elastic medium to a set of sharp and dense pinning centers is shown to be controlled by non linear...
