Absence of sizable superconductivity in hydrogen boride: A first-principles study
(APS, 2022-12-12)
The recently synthesized hydrogen boride monolayer in the Cmmm phase is a promising superconductor due to its similarity to MgB2 and the large hydrogen content in its structure. Making use of first-principles calculations ...
Ab initio study of metastable occupation of tetrahedral sites in palladium hydrides and its impact on superconductivity
(APS, 2023-01-11)
A recent experimental work on palladium hydrides suggested that metastable structures with hydrogen atoms occupying tetrahedral sites could lead to superconductivity above 50 K, a huge increase compared to the 9 K critical ...
The 2021 room-temperature superconductivity roadmap
(IOP, 2022-03-03)
Designing materials with advanced functionalities is the main focus of contemporary solid-state physics and chemistry. Research efforts worldwide are funneled into a few high-end goals, one of the oldest, and most fascinating ...
Excitonic insulator to superconductor phase transition in ultra-compressed helium
(Springer Nature, 2023-07-25)
Helium, the second most abundant element in the universe, exhibits an extremely large electronic band gap of about 20 eV at ambient pressures. While the metallization pressure of helium has been accurately determined, thus ...
Ab initio study of the structural, vibrational, and optical properties of potential parent structures of nitrogen-doped lutetium hydride
(APS, 2023-08-28)
The recent report of near-ambient conditions superconductivity in a nitrogen-doped lutetium hydride has inspired a large number of experimental studies with contradictory results. We model from first principles the physical ...
van der Waals driven anharmonic melting of the 3D charge density wave in VSe2
(Nature, 2021-01-27)
Understanding of charge-density wave (CDW) phases is a main challenge in condensed matter due to their presence in high-Tc superconductors or transition metal dichalcogenides (TMDs). Among TMDs, the origin of the CDW in ...
Anharmonicity Reveals the Tunability of the Charge Density Wave Orders in Monolayer VSe2
(American Chemical Society, 2023-02)
VSe2 is a layered compound that has attracted great attention due to its proximity to a ferromagnetic state that is quenched by its charge density wave (CDW) phase. In the monolayer limit, unrelated experiments have reported ...
Quantum structural fluxion in superconducting lanthanum polyhydride
(Nature Communications, 2023-03-25)
The discovery of 250-kelvin superconducting lanthanum polyhydride under high pressure marked a significant advance toward the realization of a room‐temperature superconductor. X-ray diffraction (XRD) studies reveal a ...
Prediction of ambient pressure conventional superconductivity above 80 K in hydride compounds
(Nature Research, 2024-02-28)
The primary challenge in the field of high-temperature superconductivity in hydrides is to achieve a superconducting state at ambient pressure rather than the extreme pressures that have been required in experiments so ...
Assessing the feasibility of near-ambient conditions superconductivity in the Lu-N- H system
(Springer Nature, 2024-04-24)
The report of near-ambient superconductivity in nitrogen-doped lutetium hydrides (Lu-N-H) has generated a great interest. However, conflicting results raised doubts regarding superconductivity. Here, we combine high-throughput ...
