Abstract The terahertz (0.1–10 THz) range represents a fast-evolving research and industrial
field. The great interest for this portion of the electromagnetic spectrum, which lies between …

Quantum-mechanical phenomena underpin the behaviour of quantum materials at the
microscopic level. The description of several essential properties of these materials …

We present a novel, structurally simple, multifunctional broadband absorber. It consists of a
patterned vanadium dioxide film and a metal plate spaced by a dielectric layer. Temperature …

In recent years, metasurfaces have attracted considerable interest for their unprecedented
capabilities to manipulate intensity, phase, and polarization of an electromagnetic wave …

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 …

The reversible, ultrafast, and multistimuli responsive phase transition of vanadium dioxide
(VO2) makes it an intriguing “smart” material. Its crystallographic transition from the …

Electron–electron interactions can render an otherwise conducting material insulating, with
the insulator–metal phase transition in correlated-electron materials being the canonical …

A thermally tunable terahertz window based on the combination of a metamaterial and the
phase change material VO2 is proposed. The window is composed of two vanadium oxide …

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 …

First-order phase transitions in solids are notoriously challenging to study. The combination
of change in unit cell shape, long range of elastic distortion and flow of latent heat leads to …
