The structure of molecules, particularly the dynamic changes in structure, plays an essential
role in understanding physical and chemical phenomena. Time-resolved (TR) scattering …

Halide perovskites emerged as a revolutionary family of high-quality semiconductors for
solar energy harvesting and energy-efficient lighting. There is mounting evidence that the …

Crystal lattice fluctuations, which are known to influence phase transitions of quantum
materials in equilibrium, are also expected to determine the dynamics of light-induced phase …

Stacking nonpolar, monolayer materials has emerged as an effective strategy to harvest
ferroelectricity in two-dimensional (2D) van der Waals (vdW) materials. At a particular …

Perovskite oxides exhibit a rich variety of structural phases hosting different physical
phenomena that generate multiple technological applications. We find that topological …

Ferroelectric materials exhibit a rich range of complex polar topologies, but their study under
far-from-equilibrium optical excitation has been largely unexplored because of the difficulty …

The technique of coupling cation ordering with other microscopic degrees of freedom was
employed to induce magnetic polar phenomena within the materials belonging to the double …

Do** ferroelectrics with carriers is often detrimental to polarization. This makes the design
and discovery of metals that undergo a ferroelectriclike transition challenging. In this Letter …

The functional properties of complex oxides, including magnetism and ferroelectricity, are
closely linked to subtle structural distortions. Ultrafast optical excitations provide the means …

We reveal a photoinduced control of ferroelectricity in hybrid-improper ferroelectric
superlattices, using ab initio theory. Along with a notable photostriction effect, thermalized …
