Metal-halide perovskites (MHPs) are attracting considerable interest for optoelectronic applications, with Cs_{2}AgBiBr_{6} one of the main contenders among lead-free systems. Cs_{2}AgBiBr_{6} crystallizes in a nominally double-perovskite structure,

CrGeTe3 is a van der Waals honeycomb ferromagnet, known for exhibiting strong coupling between lattice and spin degrees of freedom. Here, Chen et al perform neutron scattering on CrGeTe3, find a broadened spin-wave excitation resulting from zero-temp

Photoinduced ultrafast phase transitions can generate quasiequilibrium states with novel emergent properties modulated by the interplay of electronic and lattice degrees of freedoms. Therefore, accurately probing transient atomic structures and their

There is growing interest in using ultrafast light pulses to drive functional materials into nonequilibrium states with novel properties. The conventional wisdom is that above-gap photoexcitation behaves similarly to raising the electronic temperatur

The improper ferroelectric mechanism of YMnO3 has been difficult to observe directly but is important for understanding its other interesting properties such as multiferroicity. Bansal et al. use neutron scattering and ab initio calculations to show
