The ever-growing need for next-generation electronic and magnetic devices calls for new solutions for the engineering of quantum materials, in terms of miniaturization, energy consumption and speed compared to reference benchmarks, e.g. 18 ps for the Larmor magnetization switching. A new paradigm has emerged: the effect of the decrease of dimensionality in magnetic materials is recently being given a large deal of attention. [more]

The study of the suppression of an order parameter by an external perturbation and the following recovery of the broken-symmetry phase is a problem relevant to systems even beyond condensed matter physics. In the context of pump-probe experiments, it has been tackled considering the suppression of the charge density wave order parameter in several compounds, and it was found a relevant role played by the fluctuations [1,2].
