Accelerating phase field simulations to understand liquid-metal dealloying
News Article, March 3, 2025 • Liquid metal dealloying. The initial species fields (cA and cB at t=0) are contaminated with low-amplitude random white noise (left fields). Given the chaotic nature of the dealloying process, the initial noise perturbation eventually leads to widely different solid phase fields at late time (e.g., right fields, at t=6⁢μs, after 6 million time steps). When...

Using the power of “super-small” to solve large-scale scientific problems
News Article, October 13, 2022 • Sandia builds a testbed for powerful quantum computing hardware and scientific applications. Try this thought experiment: imagine a small measurable quantity of something—perhaps a grain of sand or a point of light—then cut it in half, again and again. When you reach the smallest quantity, such as a photon of...
