Stability and Superconductivity of Ternary Polyhydrides
Dmitrii V. Semenok, Di Zhou, Wuhao Chen +8
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloy…
Radio-Frequency Method for Detecting Superconductivity Under High Pressure
Dmitrii V. Semenok, Di Zhou, Jianbo Zhang +5
We introduce a contactless technique for probing superconductivity and magnetic ordering transitions in micron-sized samples under extreme pressure. Utilizing a multistage Lenz len…
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…
Observation of the Josephson effect in superhydrides: DC SQUID based on (La,Ce)H with operating temperature of 179 K
Dmitrii V. Semenok, Ivan A. Troyan, Di Zhou +3
Among known materials, hydride superconductors have the highest critical temperatures and are very promising as a basis for electronic sensors. Superconducting quantum interference…
Evidence for Pseudogap Phase in Cerium Superhydrides: CeH and CeH
Dmitrii Semenok, Jianning Guo, Di Zhou +9
Polyhydride superconductors have been shown to possess metallic properties with a Bardeen-Cooper-Schrieffer-type superconducting ground state. Here, we provide evidence for unconve…
Imaging the Meissner effect and flux trapping in a hydride superconductor at megabar pressures using a nanoscale quantum sensor
Prabudhya Bhattacharyya, Wuhao Chen, Xiaoli Huang +24
By directly altering microscopic interactions, pressure provides a powerful tuning knob for the exploration of condensed phases and geophysical phenomena. The megabar regime repres…
Enhancement of the superconducting critical temperature realized in the La-Ce-H system at moderate pressures
Wuhao Chen, Xiaoli Huang, Dmitrii V. Semenok +4
Covalent and ionic polyhydrides have become the two main camps in searching for the high-temperature superconductors under pressure. They have been considered as important platform…
High-Temperature Superconductivity in Cerium Superhydrides
Wuhao Chen, Dmitrii V. Semenok, Xiaoli Huang +5
The discoveries of high-temperature superconductivity in H3S and LaH10 have excited the search for superconductivity in compressed hydrides. In contrast to rapidly expanding theore…
Quantum phase transitions in superconductor--quantum-dot--superconductor Josephson structures with attractive intradot interaction
Yu-Chun Hsu, Wu-Jing Chen, Chien-Te Wu
We theoretically study the superconducting proximity effect in a quantum dot coupled to two superconducting leads when the intradot interaction between electrons is made attractive…
High-Pressure Synthesis of Barium Superhydrides: Pseudocubic BaH12
Wuhao Chen, Dmitrii V. Semenok, Alexander G. Kvashnin +9
Following the discovery of high-temperature superconductivity in the La-H system, where for the recently discovered fcc-LaH10 a record critical temperature Tc = 250 K was achieved…
Superconductivity and Equation of State of Distorted fcc-Lanthanum above Megabar Pressures
Wuhao Chen, Dmitrii V. Semenok, Ivan A. Troyan +4
Lanthanum (La) is the first member of the rare-earth series of elements that has recently raised considerable interest because of its unique high-Tc superhydride LaH10. Although se…
