This work addresses dynamical aspects of quantum criticality in two space dimensions. It probes two energy scales: the amplitude (Higgs) mode, which describes f

This thesis presents and discusses recent optical low-temperature experiments on disordered NbN, granular Al thin-films, and the heavy-fermion compound CeCoIn5,

Ferromagnetism of metallic systems, especially those including transition metals, has been a controversial subject of modern science for a long time. This contr
