We use machine learning and free energy methods to overcome the limitations of quantum mechanical simulations, and characterize hydrogen diffusion, superionic transitions, and phase behaviors of water at extreme conditions. We predict that a close-packed superionic phase with mixed stacking is stable over a wide temperature and pressure range, while a body-centered cubic phase is only thermodynamically stable in a small window but is kinetically favored. Our phase boundaries, which are consistent with the existing-albeit scarce-experimental observations, help resolve the fractions of insulating ice, different superionic phases, and liquid water inside of ice giants."}],"article_number":"2103.09035","publication_status":"submitted","publication":"arXiv","title":"Predicting the phase behaviors of superionic water at planetary conditions","author":[{"id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9","last_name":"Cheng","orcid":"0000-0002-3584-9632","first_name":"Bingqing","full_name":"Cheng, Bingqing"},{"full_name":"Bethkenhagen, Mandy","first_name":"Mandy","last_name":"Bethkenhagen"},{"full_name":"Pickard, Chris J.","first_name":"Chris J.","last_name":"Pickard"},{"full_name":"Hamel, Sebastien","first_name":"Sebastien","last_name":"Hamel"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2103.09035"}],"_id":"9696"}
