Metal-to-insulator transition (MIT) behaviors accompanied by a rapid reversible phase
transition in vanadium dioxide (VO2) have gained substantial attention for investigations into …

The phase transition of VO 2 from a monoclinic insulator to a rutile metal, which occurs
thermally at TC= 340 K, can also be driven by strong photoexcitation. The ultrafast dynamics …

The complex interplay among several active degrees of freedom (charge, lattice, orbital, and
spin) is thought to determine the electronic properties of many oxides. We report on …

Using light to control transient phases in quantum materials is an emerging route to
engineer new properties and functionality, with both thermal and non-thermal phases …

Coulomb correlations can manifest in exotic properties in solids, but how these properties
can be accessed and ultimately manipulated in real time is not well understood. The …

Using femtosecond time-resolved photoelectron spectroscopy we demonstrate that
photoexcitation transforms monoclinic VO 2 quasi-instantaneously into a metal. Thereby, we …

The insulator-metal transition (IMT) of vanadium dioxide (VO2) has remained a long-
standing challenge in correlated electron physics since its discovery five decades ago. Most …

We establish time-resolved high harmonic generation (tr-HHG) as a powerful spectroscopy
method for tracking photoinduced dynamics in strongly correlated materials through a …

We combine ultrafast electron diffraction and time-resolved terahertz spectroscopy
measurements to link structure and electronic transport properties during the photoinduced …

As the quest for active photonic devices continues, materials with exotic and exploitable
properties have become paramount to enable new advancements. In recent years, phase …
