Our large-scale molecular-dynamics simulations with a machine-learning potential indicate that, amongst these bcc ice phases, ices VII, VII′ and X are the same thermodynamic phase under different conditions, whereas superionic ice VII″ has a first-order phase boundary with ice VII′. Moreover, at about 300 GPa, the transformation between ice X and the Pbcm phase has a sharp structural change but no apparent activation barrier, whilst at higher pressures the barrier gradually increases. Our study thus clarifies the phase behaviour of the high-pressure ices and reveals peculiar solid–solid transition mechanisms not known in other systems."}],"department":[{"_id":"BiCh"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2022-08-21T22:01:55Z","oa":1,"oa_version":"Published Version","scopus_import":"1","publisher":"Springer Nature","status":"public","title":"Thermodynamics of high-pressure ice phases explored with atomistic simulations","quality_controlled":"1","doi":"10.1038/s41467-022-32374-1","author":[{"last_name":"Reinhardt","first_name":"Aleks","full_name":"Reinhardt, Aleks"},{"first_name":"Mandy","last_name":"Bethkenhagen","full_name":"Bethkenhagen, Mandy"},{"full_name":"Coppari, Federica","last_name":"Coppari","first_name":"Federica"},{"full_name":"Millot, Marius","first_name":"Marius","last_name":"Millot"},{"last_name":"Hamel","first_name":"Sebastien","full_name":"Hamel, Sebastien"},{"orcid":"0000-0002-3584-9632","id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9","full_name":"Cheng, Bingqing","first_name":"Bingqing","last_name":"Cheng"}],"has_accepted_license":"1","publication":"Nature Communications","publication_identifier":{"eissn":["2041-1723"]},"external_id":{"isi":["000838655300022"],"pmid":["35948550"]},"citation":{"short":"A.
