Caption
Free-energy landscape showing the transition pathway from coesite with silicon atoms surrounded by four oxygen atoms (blue, on the left) to the high pressure post-stishovite with silicon atoms surrounded by six oxygen atoms (green, on the right). Evidence of the new phases can be seen in between the two orange peaks. Image is provided courtesy of Ho-Kwang Mao.
