 **Topological and quantum critical properties of the interacting Majorana chain model**
 
 Despite our very good understanding of several models in one dimension involving interacting (Dirac) fermions, the case of Majorana fermions has remained relatively unexplored. This is probably due to the fact that Majorana particles are not found as elementary objects in nature. Nevertheless, 20 years ago, in the context of modeling p-wave superconducting wires, Alexei Kitaev proposed a very influential yet simple toy model in which unpaired Majorana fermions can appear as edge states. In this talk I will present the basics of this problem and explore the non-trivial effects of interactions in such a system, building on DMRG and self-consistent mean-field approaches. If time permits, I may also touch on disorder effects...

 One way to contribute to filling this gap is the use of simple solvable models. Here, we will examine results for the symmetric half-filled Hubbard dimer, which allows us to cover the full range from vanishing to strong correlation. Our aim is to design an optimal way to use MBPT, remaining at low order, with a particular focus on the design of effective interactions. This will include combinations of MBPT with time-dependent density functional theory.
 
 We will illustrate how the simple model allows us to benchmark, and also to understand and to improve results. Finally, we will also discuss limitations of the extrapolation of results from the Hubbard dimer to real systems.

 ### David Gontier (CEREMADE, Paris) 
 
 **Phase transition in the Peierls / SSH model**
 
 The Peierls/SSH model is a simple one-dimensional model used to describe molecular chains such as polyacetylene. In this model, we consider a distortion energy between the atoms, and an electronic quantum energy given by a tight-binding model. Peierls showed that it was energetically favorable for the chain to dimerize (hence the structure …=C-C=C-… of polyacetylene). In this talk, we will study the phase diagram of this model, when we add temperature. We show the existence of a critical temperature above which the chain no longer dimerizes. Work in collaboration with Adéchola Kouandé and Éric Séré.

 **Dissipative impurity dynamics in one dimensional quantum liquids**
 
 In the first part of the talk we will consider a system of bosons with contact interaction in one dimension, the Lieb-Liniger model. Then, we will study the motion of a slow impurity (a foreign particle) through this system. While at zero temperature the impurity motion is frictionless, at low temperatures finite friction appears due to scattering off thermally excited quasiparticles. We will derive analytical results for the friction force within a microscopic theory and uncover interesting regimes of the impurity dynamics.

 ### Marie Labeye (ENS, Paris)
 
 **Time dependent models for strong field physics**
 
 In this presentation, I will present several simple systems that allow us to describe complex time-dependent processes. In particular I will show that low dimensional systems are powerful tools to model the strong-field driven dynamics of atoms and molecules. Indeed, these model systems allow to directly solve the Time-Dependent Schrödinger Equation and therefore accurately represent highly non-linear processes such as tunnel ionization or high-order harmonic generation.
