Bosonization technique for one-dimensional fermions out of equilibrium is developed in the
framework of the Keldysh action formalism. We first demonstrate how this approach is …

We study the transport properties of interacting electrons in a disordered quantum wire
within the framework of the Luttinger-liquid model. We demonstrate that the notion of weak …

A one-dimensional system of interacting electrons out of equilibrium is studied in the
framework of the Luttinger liquid model. We analyze several setups and develop a theory of …

We study the transport properties of interacting electrons in a disordered quantum wire
within the framework of the Luttinger liquid model. The conductivity at finite temperature is …

We study the edge transport in two-dimensional topological insulators which is carried by
interacting helical fermions. This transport is ballistic when it is protected by time-reversal …

We develop a theory of tunneling spectroscopy of interacting electrons in a nonequilibrium
quantum wire coupled to reservoirs. The problem is modeled as an out-of-equilibrium …

Nous montrons comment les oscillations de Friedel induites par la présence d'une impureté
permettent de sonder de manière inattendue et tout à fait remarquable les propriétés …

We have studied low-temperature properties of interacting electrons in a one-dimensional
quantum wire (Luttinger liquid) side-hybridized with a single-level impurity. The hybridization …

We develop a bosonization technique for one-dimensional fermions out of equilibrium. The
approach is used to study a quantum wire attached to two electrodes with arbitrary energy …

This thesis comprises two parts centered around the functional renormalization-group
framework: in the first part, I study the role of symmetries and conservation laws in …
