Mesoscopic transport in superconductor-graphene hybrid nanostructures
This thesis presents a study of electronic transport in exfoliated graphene at low temperature. A first set of experiment at 4K on samples connected by titanium/gold... -
Channel Mixing and Spin transport in the Integer Quantum Hall Effect
Edge states are one-dimensional transport channels, emerging in quantum wells in the integer Quantum Hall regime, with remarkable properties of chirality and quantum... -
Electron quantum optics in quantum Hall edge channels
This thesis is devoted to the implementation of quantum optics experiments in a ballistic quantum conductor, with single charge resolution. A mesoscopic capacitor... -
Edge states and supersymmetric sigma models
A fundamental property of the quantum Hall effect is the presence of edge states at the boundary of the sample, robust against localization and responsible for the... -
From Local to Non-Local Transport : Percolation in Quantum Hall Systems, Cros...
This thesis consists of two independent parts. The first one deals with transport in two dimensional electron gases in the regime of the quantum Hall effect. In the... -
Short-time Hanbury-Brown and Twiss correlation of a single-electron beam in b...
This thesis is devoted to the study of current correlation of single-electron beams in a ballistic quantum conductor. A mesoscopic capacitor is used as an on-demand... -
Etude de l'intrication dans l'effet Hall quantique fractionnaire
In the past decades it has become clear that Landau's theory of phase transitions which involves the appearance of a broken-symmetry order parameter does not apply to...
