The raman signal of a hindered rotor
Peter I. C. Cooke, Ioan B. Magdǎu, Miriam Peña-Alvarez +6
We present a method for calculation of Raman modes of the quantum solid phase I solid hydrogen and deuterium. We use the mean-field assumption that the quantised excitations are lo…
The Icosahedral (H Supermolecule
Graeme J. Ackland, Jack Binns, Ross Howie +1
We investigate a range of possible materials containing the supermolecular form of hydrogen comprising 13 hydrogen molecules arranged in an icosahedral arrangement. This supermolec…
On the Reactivity of Hydrogen-Helium and Hydrogen-Nitrogen at High Pressures
Robin Turnbull, Mary-Ellen Donnelly, Mengnan Wang +6
Through a series of Raman spectroscopy studies, we investigate the behaviour of hydrogen-helium and hydrogen-nitrogen mixtures at high pressure across wide ranging concentrations.…
Structure and metallicity of phase V of hydrogen
Bartomeu Monserrat, Neil D. Drummond, Philip Dalladay-Simpson +5
A new phase V of hydrogen was recently claimed in experiments above 325 GPa and 300 K. Due to the extremely small sample size at such record pressures the measurements were limited…
Crossover between liquid-like and gas-like behaviour in CH4 at 400 K
D. Smith, M. A. Hakeem, P. Parisiades +10
We report experimental evidence for a crossover between a liquid-like state and a gas-like state in fluid methane (CH4). This crossover is observed in all of our experiments, up to…
High-pressure behavior of superconducting boron-doped diamond
Mahmoud Abdel-Hafiez, Dinesh Kumar, R. Thiyagarajan +8
This work investigates the high-pressure structure of freestanding superconducting ( = 4.3\,K) boron doped diamond (BDD) and how it affects the electronic and vibrational pr…
