  • A molecular perspective on the limits of life: Enzymes under pressure 
    Huang, Q.; Tran, K.N.; Rodgers, J.M.; Bartlett, D.H.; Hemley, R.J.; Ichiye, T. (Condensed Matter Physics, 2016)
    From a purely operational standpoint, the existence of microbes that can grow under extreme conditions, or "extremophiles", leads to the question of how the molecules making up these microbes can maintain both their structure ...
  • Broken symmetry phase transition in solid HD: a manifestation of quantum orientational melting 
    Freiman, Yu.A.; Tretyak, S.M.; Jezowski, A.; Hemley, R.J. (Физика низких температур, 1998)
    Theoretical study of the broken symmetry phase (BSP) transition line in solid HD reveals that its anomalous features provide evidence for quantum orientational melting. The observations of unusual reentrant behavior is a ...
  • Developments in synthesis, characterization, and application of large, high-quality CVD single crystal diamond 
    Liang, Q.; Meng, Y.-F.; Yan, C.-S.; Krasnicki, S.; Lai, J.; Hemawan, K.; Shu, H.; Popov, D.; Yu, T.; Yang, W.; Mao, H.K.; Hemley, R.J. (Сверхтвердые материалы, 2013)
    Single crystal diamond synthesis by microwave plasma chemical vapor deposition at rapid growth rate has considerably advanced in the past few years. Developments have been made in growth, optical quality, and mechanical ...
  • Molecular rotation in p-H₂ and o-D₂ in phase I under pressure 
    Freiman, Yu.A.; Tretyak, S.M.; Goncharov, A.F.; Mao, H.; Hemley, R.J. (Физика низких температур, 2011)
    The orientational order parameter, rotational ground-state energy, and lattice distortion parameter (the deviation of the c/a ratio from the ideal hcp value 1.633) in hcp lattice of phase I of p-H₂ and o-D₂ are calculated ...
  • Ortho–para conversion in the solid hydrogens at high pressures 
    Strzhemechny, M.A.; Hemley, R.J. (Физика низких температур, 2003)
    At low pressures the ortho–para conversion in H₂ and D₂ is a slow process governed by the magnetic dipole interaction of nuclear magnetic moments, phonons being the main energy sink. As the pressure is raised to a few GPa ...
  • Vibrational dynamics of solid molecular nitrogen to megabar pressures 
    Goncharov, A.F.; Gregoryanz, E.; Mao, H.-K.; Hemley, R.J. (Физика низких температур, 2001)
    We report the results of Raman and synchrotron infrared absorption measurements of several molecular phases of solid nitrogen to pressures above 100 GPa (300 K). Low- temperature vibrational spectra to 45 GPa are also ...
  • Ориентационное упорядочение в твердых водородах c J = 1 при наличии кристаллического поля 
    Aнцыгина, Т.Н.; Третьяк, С.М.; Фрейман, Ю.А.; Hemley, R.J. (Физика низких температур, 2003)
    Исследована система квантовых линейных ротаторов с квантовым вращательным числом J = 1, находящихся в кристаллическом поле. Получено уравнение для ориентационного параметра порядка, найдены критические параметры, кривая ...
