Les signatures de l’existence des phonons sont omniprésentes dans les propriétés des matériaux. En première approximation, on peut scinder l'effet des phonons sur la structure électronique en deux contributions. D’une part, l'interaction é

This thesis is devoted to the study of reservoir-induced dynamics and reservoir computing in the context of quantum optics, structured along three major axes: (1) the dissipative dynamics of a quantum system in the presence of the environment (modele

Dans la description à basse énergie de systèmes fortement corrélés, les champs de jauge peuvent émerger comme excitations collectives couplées à des quasiparticules fractionalisées. En particulier, certains aimants bidimensionnels dits frust

Active matter is intrinsically out of equilibrium because energy is converted into systematic motion by its constituents, and exhibit fascinating collective phenomena. One of them is phase separation between dense and dilute regions which, unlike in

Studying how a system responds to an external perturbation reveals many features about its structure or the underlying interactions between its constituents. In the case of atomic nuclei, such information plays a prominent role when one aims at under

The field of ultrafast structural dynamics is based on remarkable developments of available pulse sources, from THz to x-rays. Currently, pump-probe techniques operate on the femtosecond time scales, i.e. faster than atomic motions. Typically, a lase

When light and matter are weakly coupled, they can be described as two distinctive systems exchanging quanta of energy. By contrast, when their coupling strength becomes very large, the systems hybridize and form compounds that cannot be described in
