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 ...
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 ...
Large impact of phonon lineshapes on the superconductivity of solid hydrogen
(Springer Nature, 2024-05-09)
Phonon anharmonicity plays a crucial role in determining the stability and vibrational properties of high-pressure hydrides. Furthermore, strong anharmonicity can render phonon quasiparticle picture obsolete questioning ...
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 ...
