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 …

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 …

In a generalization of the latest achievements in this field, and as a pattern of massive
applications, we present here the Jahn–Teller effect (JTE) and pseudo-JTE (PJTE) as …

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 …

Manipulation of ferroelectric polarization and associated domain is at the heart of
ferroelectric‐based applications. Polarization switching is typically achieved by a static or …

Optical pulses are routinely used to drive dynamic changes in the properties of solids. In
quantum materials, many new phenomena have been discovered, including ultrafast …

The ability to switch ferroics (ferro-, ferri-, antiferromagnets, ferroelectrics, multiferroics)
between two stable bit states is one of the keystones of modern data storage technology …

Twisted light carries a nonzero orbital angular momentum, that can be transferred from light
to electrons and particles ranging from nanometers to micrometers. Up to now, the interplay …

The collective dynamics of topological structures,,,,–are of interest from both fundamental
and applied perspectives. For example, studies of dynamical properties of magnetic vortices …

This review discusses picosecond ultrasonics experiments using ultrashort hard x-ray probe
pulses to extract the transient strain response of laser-excited nanoscopic structures from …
