“…[230], the authors establish time-resolved high harmonic generation for tracking photo-induced dynamics of the insulator-to-metal phase transitions in vanadium dioxide. Closely, related to this is the study by Johnson et al where they use time and spectrally resolved coherent X-ray imaging to track the light-induced insulator-to-metal phase transition in vanadium dioxide on the nanoscale with femtosecond time resolution [231] and also observed the ultrafast loss of lattice coherence in the light induced structural phase transition of di-Vanadium trioxide [232].…”

Strong--laser--field physics is a research direction that relies on the use of high-power lasers and has led to fascinating achievements ranging from relativistic particle acceleration to attosecond science. On the other hand, quantum optics has been built on the use of low photon number sources and has opened the way for groundbreaking discoveries in quantum technology, advancing investigations ranging from fundamental tests of quantum theory to quantum information processing. Despite the tremendous progress, until recently these directions have remained disconnected. This is because, the majority of the interactions in the strong-field limit have been successfully described by semi-classical approximations treating the electromagnetic field classically, as there was no need to include the quantum properties of the field to explain the observations. The link between strong--laser--field physics, quantum optics, and quantum information science has been developed in the recent past. Studies based on fully quantized and conditioning approaches have shown that intense laser--matter interactions can be used for the generation of controllable entangled and non-classical light states. These achievements open the way for a vast number of investigations stemming from the symbiosis of strong--laser--field physics, quantum optics, and quantum information science. Here, after an introduction to the fundamentals of these research directions, we report on the recent progress in the fully quantized description of intense laser--matter interaction and the methods that have been developed for the generation of non-classical light states and entangled states. Also, we discuss the future directions of non-classical light engineering using strong laser fields, and the potential applications in ultrafast and quantum information science.

“…Moreover, the observation of a threshold proves the existence of a critical value of electronic excitation which triggers the self-amplification of IMT at macroscopic scale. This change of scale from local to macroscopic manifests also by a loss of coherence of inphase optical phonons [45]. A theoretical study on V2O3, based on a two orbital model, shows that the excess population of electrons in the upper orbital and holes in lower orbital may lead to a gap collapse above a threshold [46].…”

Ultrafast physics opens new avenues for directing materials to different functional macroscopic states on non-thermal dynamical pathways. In any phase transition involving volume and/or ferroelastic deformation, an often overlooked mechanism emerges whereby photoinduced elastic waves drive the transition. However, a comprehensive physical picture of transformation dynamics which includes acoustic scale propagation remained elusive. Here we show that such a strain wave mechanism drives the ultrafast insulator-to-metal phase transition (IMT) in the V2O3 Mott material. We discuss the underlying physics based on time-resolved optical reflectivity and X-ray diffraction probing granular thin films. We evidence the role of strain wave mechanisms in ultrafast changes either with or without symmetry breaking. We reveal inverse ferroelastic shear occurring before the IMT propagating in the wake of compressive strain wave. These dynamics are shown to be governed by the domain size and the film thickness, respectively. A fluence threshold is evidenced for the onset of IMT at macroscopic scale, as well as phase separation at intermediate fluence and complete transformation at saturating fluence. We clarify the morphological conditions for the ultrafast IMT that is favoured in granular thin films, and hindered in single crystals. The resulting physical picture shed new light on ultrafast phase transitions in quantum materials and future devices based ond Mott insulators.
