Metallic Hydrogen: A Liquid Superconductor?
Craig M. Tenney, Zachary F. Croft, Jeffrey M. McMahon
Metallic hydrogen is expected to exhibit remarkable physics. Of particular interest in this work is the possibility of high-temperature superconductivity. Comparing calculations of…
Temperature-dependent mechanical properties of ZrC and HfC from first principles
Jin Zhang, Jeffrey M. McMahon
In order to gain insight into the effect of elevated temperature on mechanical performance of ZrC and HfC, the temperature-dependent elastic constants of these two carbides have be…
The pseudopotential approach within density-functional theory: the case of atomic metallic hydrogen
Jin Zhang, Jeffrey M. McMahon
Internal energies, enthalpies, phonon dispersion curves, and superconductivity of atomic metallic hydrogen are calculated. The (standard) use pseudopotentials in density-functional…
High-Temperature Superconductivity in the Ti--H System at High Pressures
Jin Zhang, Jeffrey M. McMahon, Artem R. Oganov +4
Search for stable high-pressure compounds in the Ti--H system reveals the existence of titanium hydrides with new stoichiometries, including Ibam-TiH, I4/m-TiH,…
On the possibility of metastable metallic hydrogen
Craig M. Tenney, Keeper L. Sharkey, Jeffrey M. McMahon
Metallic hydrogen is expected to exhibit remarkable physics. Examples include high-temperature superconductivity and possible novel types of quantum fluids. These could have revolu…
Density functionals from deep learning
Jeffrey M. McMahon
Density-functional theory is a formally exact description of a many-body quantum system in terms of its density; in practice, however, approximations to the universal density funct…
