We have studied the spin dynamics of an individual Mn atom embedded a CdTe quantum dot. Our results show that the Mn spin relaxation is faster when the quantum dot...

Magnetic frustration helps destabilizing conventional Néel order at T = 0 in dimensions 2, and therefore allows the emergence of new original quantum phases. The S=1/2...

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

The rotation of the plane of polarization of light upon transmission through a magnetized medium is known as Faraday rotation (FR). In non-magnetic semiconductors FR...

In this thesis, the interplay between electron transport and magnetization dynamics is explored in order to access to fundamental properties of ferromag- netic metal...

In my thesis I will discuss some aspects of collective dynamics of excitons and exciton-polaritons in nanoscale heterostructures. In the first Chapter I will make a...

This PhD thesis is at a cross-road between three different fields : the spintronics which uses the spin degree of freedom of the electron to build new devices ; the...
