Superconductivity of and polyhydrides
Ivan A. Kruglov, Dmitrii V. Semenok, Hao Song +8
We explore high-pressure phase stability and superconductivity of lanthanum hydrides (m=4-11,16). We predict stability of a hitherto unreported polyhydride -$LaH_{1…
On Distribution of Superconductivity in Metal Hydrides
Dmitrii V. Semenok, Ivan A. Kruglov, Igor A. Savkin +2
Using the data on the superconducting critical temperature () for a number of metal hydrides, we found a rule that makes it possible to predict the maximum based onl…
Synthesis of clathrate cerium superhydride CeH9 below 100 GPa with atomic hydrogen sublattice
Nilesh P. Salke, M. Mahdi Davari Esfahani, Youjun Zhang +7
Hydrogen-rich superhydrides are believed to be very promising high-Tc superconductors as they are expected to mimic characteristics of metallic hydrogen. Recent experiments discove…
Actinium hydrides , , as high-temperature conventional superconductors
Dmitrii V. Semenok, Alexander G. Kvashnin, Ivan A. Kruglov +1
Stability of numerous unexpected actinium hydrides was predicted via evolutionary algorithm USPEX. Electron-phonon interaction was investigated for the hydrogen-richest and most sy…
Boron monosulfide: equation of state and pressure-induced phase transition
Kirill A. Cherednichenko, Ivan A. Kruglov, Artem R. Oganov +3
Quasi-hydrostatic compression of rhombohedral boron monosulfide (r-BS) has been studied up to 50 GPa at room temperature using diamond-anvil cells and angle-dispersive synchrotron…
