Yttrium Superhydrides Revisited: Advanced Experimental and Theoretical Studies of YH, YH and YH
Dmitrii V. Semenok, Pedro N. Ferreira, Di Zhou +10
Yttrium polyhydrides are benchmark materials in high-pressure superconductivity, yet several key properties of the Y-H system remain insufficiently characterized. Here we combine c…
Fundamental limits on the electron-phonon coupling and superconducting
Dmitrii V. Semenok, Boris L. Altshuler, Emil A. Yuzbashyan
Fundamental upper bounds on the electron-phonon interaction strength and superconducting transition temperature in metals are established based on the intrinsic instability o…
Ternary superhydrides under pressure of Anderson's theorem: Near-record superconductivity in (La,Sc)H
Dmitrii V. Semenok, Ivan A. Troyan, Di Zhou +12
Lanthanum-hydrogen system and its derivatives remain among the most promising for achieving room-temperature superconductivity. In this study, we examined the formation of ternary…
Superconducting memory and trapped magnetic flux in ternary lanthanum polyhydrides
Dmitrii V. Semenok, Andrei V. Sadakov, Di Zhou +6
Superconducting memory is a promising technology for data storage because of its speed, high energy efficiency, non-volatility, and compatibility with quantum computing devices. Ho…
