Implications of an improved water equation of state for water-rich planets
Chenliang Huang, David R. Rice, Zachary M. Grande +6
Water (HO), in all forms, is an important constituent in planetary bodies, controlling habitability and influencing geological activity. Under conditions found in the interio…
Ultra-fast yttrium hydride chemistry at high pressures via non-equilibrium states induced by x-ray free electron laser
Emily Siska, G. Alexander Smith, Sergio Villa-Cortes +24
Controlling the formation and stoichiometric content of desired phases of materials has become a central interest for the study of a variety of fields, notably high temperature sup…
Lower pressure phases and metastable states of superconducting photo-induced carbonaceous sulfur hydride
G. Alexander Smith, Ines E. Collings, Elliot Snider +9
Room-temperature superconductivity was recently discovered in carbonaceous sulfur hydride (C-S-H) close to 3\,Mbar. We report significant differences in the superconducting respons…
Decoupling lattice and magnetic instabilities in frustrated CuMnO
Keith V. Lawler, Dean Smith, Shaun R. Evans +8
The MnO delafossites (=Na, Cu), are model frustrated antiferromagnets, with triangular layers of Mn~spins. At low temperatures (=65 K), a $C2/m \rightarro…
Coupled plastic strain- and stress-induced phase transformations and microstructure evolution in Fe-7%Mn alloy in dynamic rotational diamond anvil cell
Sorb Yesudhas, Mrinmay Sahu, Valery I. Levitas +2
The first experiments in dynamic rotational diamond anvil cell (dRDAC) on severe plastic deformation (SPD) and BCC<->HCP phase transformation (PT) at pressure up to 27.6 GPa, rotat…
Observation of Conventional Near Room Temperature Superconductivity in Carbonaceous Sulfur Hydride
Hiranya Pasan, Elliot Snider, Sasanka Munasinghe +21
The phenomenon of high temperature superconductivity, approaching room temperature, has been realized in a number of hydrogen-dominant alloy systems under high pressure conditions1…
