Using a nanosecond X-ray source, they probed the atomic structure of MgO under these conditions. The results were striking: the B1 to B2 phase transition in MgO occurred within the 400–430 GPa ...

The lattice structure receives a large ... the nonequilibrium electronic and atomic states, ultrafast timescales, and homogeneous nucleation. Besides MgO, we also perform simulations for other ...

Instead, the optimal structure becomes a flat planar 20-atom gold island spread on the MgO surface. Turning off the applied field or reversing it’s direction results in reverting the structure ...
