Irradiation with a strong terahertz electric-field pulse is found to induce a Mott transition in an organic molecular compound. The metallization is attributed to an impulsive dielectric breakdown

Intercalation — a cornerstone of materials science with wide-ranging applications — has now been demonstrated in a superatomic crystal. A redox-active tetracyanoethylene guest was inserted into the lattice of a material consisting of alternate

Metal-oxide superlattices were found to possess coexisting phases; a ferroelectric phase and a vortex phase with electric toroidal order. Electric fields interconverted from one phase to another, potentially enabling new functionality.
