TL;DR: In the last two decades non-equilibrium spectroscopies have evolved from avant-garde studies to crucial tools for expanding our understanding of the physics of strongly correlated materials as mentioned in this paper.

TL;DR: In this article, a review of the most recent achievements in the experimental and theoretical studies of the non-equilibrium electronic, optical, structural and magnetic properties of correlated materials is presented.

TL;DR: Time-resolved optical spectroscopy of an optimally doped cuprate is used to show that the temporal evolution of the reflectivity is consistent with the electronic contribution being dominant and is able to account for the high Tc by itself.

TL;DR: In this paper, the photo-induced insulator-metal transition in VO2 was studied, correlating threshold and dynamic evolution with excitation wavelength, and it was shown that switching can only be induced with photon energies above the 670-meV gap.

TL;DR: The interplay between the many-body high-energy CuO2 excitations at 1.5 and 2 eV, and the onset of HTSC is reported, revealing an unconventional mechanism both below and above the optimal hole concentration required to attain the maximum critical temperature (Tc).
