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 …

The intriguing physics of vanadium dioxide (VO 2) makes it not only a fascinating object of
study for fundamental research on solid-state physics but also an attractive means to actively …

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 …

The Drude-Smith model has been used extensively in fitting the THz conductivities of
nanomaterials with carrier confinement on the mesoscopic scale. Here, we show that the …

Optical phase change materials (O-PCMs) are being explored for a variety of photonic
applications due to the extraordinarily large changes in optical properties that occur during …

Vanadium dioxide (VO 2) has attracted a great interest for smart coating applications
because of its promising thermochromic properties. Thermochromic performance of VO 2 is …

We describe a method for the active control of terahertz (THz) waves using vanadium
dioxide (VO 2)-embedded hybrid metamaterials (MMs). VO 2 undergoes an insulator–metal …
