In a quantum dot hybrid superconducting junction, the behavior of the supercurrent is
dominated by Coulomb blockade physics, which determines the magnetic state of the dot. In …

Behavior of quantum liquids is a fascinating topic in physics. Even in a strongly correlated
case, the linear response of a given system to an external field is described by the …

Fast measurement of small currents and even smaller fluctuations in devices with large
impedance is not trivial. Standard low frequency lock-in measurements suffer from stray …

In this thesis, the single-level correlated quantum dot attached to two BCS superconducting
leads is analyzed. A difference in the superconducting phases of the leads induces the DC …

During this thesis, we have studied the competition between two many-body effects: the
Kondo effect, which is the screening of a localized magnetic moment by the conduction …

Dans cette thèse, je me suis principalement intéressé aux effets liés aux impuretés
magnétiques dans les métaux et supraconducteurs. Dans le premier chapitre je présenterai …
