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 …

Strong optical pulses at mid-infrared and terahertz frequencies have recently emerged as
powerful tools to manipulate and control the solid state and especially complex condensed …

Nonlinear optical excitation of infrared active lattice vibrations has been shown to melt
magnetic or orbital orders and to transform insulators into metals. In cuprates, this technique …

Light-induced supercurrents chart a path forward for the electromagnetic design of emergent
materials phases and collective modes for quantum engineering applications. However …

Advances in the synthesis, growth, and characterization of complex transition metal oxides
coupled with new experimental techniques in ultrafast optical spectroscopy have ushered in …

In a superconductor, absorption of photons with an energy below the superconducting gap
leads to redistribution of quasiparticles over energy and thus induces a strong …

Abstract 'Sudden'quantum quench and prethermalization have become a cross-cutting
theme for discovering emergent states of matter,,–. Yet this remains challenging in electron …

We study the out-of-equilibrium dynamics of a Bardeen-Cooper-Schrieffer condensate
subject to a periodic drive. We demonstrate that the combined effect of drive and interactions …

In equilibrium systems amplitude and phase collective modes are decoupled, as they are
mutually orthogonal excitations. The direct detection of these Higgs and Leggett collective …

We study the dynamic response of an s-wave BCS-BEC (atomic-molecular) condensate to
detuning quenches within the two-channel model beyond the weak-coupling BCS limit. At …
