Recent progress in utilizing ultrafast light-matter interaction to control the macroscopic
properties of quantum materials is reviewed. Particular emphasis is placed on photoinduced …

The crystal structure of a solid largely dictates its electronic, optical and mechanical
properties. Indeed, much of the exploration of quantum materials in recent years including …

A review on the recent development of intense laser‐driven terahertz (THz) sources is
provided here. The technologies discussed include various types of sources based on …

“Hidden phases” are metastable collective states of matter that are typically not accessible
on equilibrium phase diagrams. These phases can host exotic properties in otherwise …

Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

The field of terahertz science and technology has been an active and thriving research area
for several decades. However, the field has recently experienced an inflection point, as …

Electromagnetic radiation in the terahertz (THz) frequency range is a fascinating
spectroscopic tool that provides resonant access to fundamental modes, including the …

We report on the demonstration of ultrafast optical reversal of the ferroelectric polarization in
LiNbO 3. Rather than driving the ferroelectric mode directly, we couple to it indirectly by …

Time-resolved, pulsed terahertz spectroscopy has developed into a powerful tool to study
charge carrier dynamics in semiconductors and semiconductor structures over the past …

Direct manipulation of the atomic lattice using intense long-wavelength laser pulses has
become a viable approach to create new states of matter in complex materials …
