Formation of charge density waves (CDW) is a symmetry breaking phenomenon found in electronic systems, which is particularly common in quasi-one-dimensional...

The physical properties of homogeneous matter at thermal equilibrium are characterized by its equation of state: a relationship between different thermodynamic...

We briefly review some important properties of superfluid flow, especially the problem of critical velocity. We then present new numerical simulation results for a...

This thesis manuscript presents experimental results on Bose-Einstein condensates in optical lattices and in the regime of fast rotation. In an optical lattice an...

The pinning of vortices is used as a probe for the identification of disorder and its effect on superconductivity in 122-type iron-based superconductors. Using a new...

In stratified rotating fluids, waves sustained by a vertical columnar vortex can be unstable due to an outward radiation of waves, a phenomenon known as the radiative...

We present a theoretical and experimental analysis of thetransverse monopole mode of a fast rotating Bose-Einsteincondensate. The condensate's rotation frequency is...

Along this thesis manuscript I shall present some emergent nonlinear phenomena in spinor exciton polariton condensates. After an introductory chapter bringing the...

The study was performed experimentally. The vortices are generated by interaction between a monochromatic wave and a horizontal thin plate used as vortex generator....

thèse CONFIDENTIELLE

We study the effect of perpendicular single-ion anisotropy, $-As_{\text{z}}^2$, on the ground-state structure and finite-temperature properties of a two-dimensional...
