Anomalous thermodynamic properties of ice XVI and metastable hydrates

Last update: March 14, 2016

A paper is published in Phys. Rev. B.     T. Yagasaki, M. Matsumoto, and H. Tanaka,  Phys. Rev. B 93, 054118 (2016).   Water is known to be an "anomalous liquid", i.e., the solid state floats on the liquid state.  It is also well known that water expands when it is cooled below 4°C.  While, water has another interesting anomalous property, in which crystal ice also expands when it is deeply cooled below 55 K.   In this research, we elucidated the mech ...
