Floquet X-Ray Scattering as a Probe of Hidden Electronic Orders
Martin Eckstein, Eva Paprotzki
We develop a theoretical framework for Floquet resonant X-ray scattering, using Floquet theory combined with the ultrashort core-hole lifetime expansion. We obtain a compact expres…

Nonthermal order by disorder
Francesco Grandi, Antonio Picano, Ronny Thomale +2
The quench dynamics of systems exhibiting cooperative or almost competitive orders in equilibrium are explored using Ginzburg-Landau theory plus fluctuations. We show that when the…

Stochastic resonance in disordered charge-density-wave systems
Francesco Valiera, Antonio Picano, Martin Eckstein
Ultrafast disordering observed after photo-excitation challenges the conventional picture of photo-induced transitions where symmetry-breaking takes place along a single collective…
