The structures are plausible. The energies are negative. The phonon spectra show no imaginary frequencies. The papers get published. Then nothing happens.</p> <p>There is a reason for that silence. The gap between a theoretically stable crystal and something you can actually synthesize in a lab — something that survives on a benchtop, in air, at room temperature — is wide enough to swallow entire classes of predicted materials. A material predicted by density functional theory may be stable at zero Kelvin in vacuum, but fall apart the moment a postdoc tries to grow it on a substrate.</p> <p>Now a collaboration between Toyota Research Institute, Toyota Central R&amp;D Labs, and the University of Tokyo has built a framework that might finally close that gap. Their approach, described in a preprint posted to arXiv on July 2, takes a list of 894 computationally stable materials and winnows it down to 25 that are actually worth trying to make in a lab.</p>
