Signatures of superconductivity near 80 K in a nickelate under high pressure

Nature, 2023
Although high-transition-temperature (high- T _c) superconductivity in cuprates has been known for more than three decades, the underlying mechanism remains unknown^ 1 – 4 .

Superconductivity in pressurized trilayer La4Ni3O10−δ single crystals

Nature, 2023
The pursuit of discovering new high-temperature superconductors that diverge from the copper-based model1–3 has profound implications for explaining mechanisms behind superconductivity and may also enable new applications4–8. Here our investigation shows

Possible High T_{c} Superconductivity in La_{3}Ni_{2}O_{7} under High Pressure through Manifestation of a Nearly Half-Filled Bilayer Hubbard Model.

Physical Review Letters, 2023
Inspired by a recent experiment showing that La_{3}Ni_{2}O_{7} exhibits high T_{c} superconductivity under high pressure, we theoretically revisit the possibility of superconductivity in this material. We find that superconductivity can take place, which

Iron pnictides and chalcogenides: a new paradigm for superconductivity

Nature, 2022
Superconductivity is a remarkably widespread phenomenon that is observed in most metals cooled to very low temperatures. The ubiquity of such conventional superconductors, and the wide range of associated critical temperatures, is readily understood in ...

Zero-field finite-momentum and field-induced superconductivity in altermagnets

Physical review B, 2023
We explore the possibilities for spin-singlet superconductivity in newly discovered altermagnets. Investigating d-wave altermagnets, we show that finite-momentum superconductivity can easily emerge in altermagnets even though they have no net ...

Investigations of key issues on the reproducibility of high-T c superconductivity emerging from compressed La3Ni2O7

Matter and Radiation at Extremes, 2023
Signatures of superconductivity near 80 K have recently been discovered in single crystals of La3Ni2O7 under pressure, which makes it a new candidate for high-temperature superconductors dominated by 3d transition elements, following the cuprate and iron-

Superconductivity

Science, 1964
The number of superconductors known in 1935 was about 80, in 1950 over 100, and when last counted more than 900. Though the growth of a field cannot be measured by a single index, these numbers symbolize what has happened to the science of superconductivity; a sequence of discoveries has steadily enlarged the scope and importance of the subject.

Superconductivity in rhombohedral trilayer graphene

Nature, 2021
To access superconductivity via the electric field effect in a clean, two-dimensional device is a central goal of nanoelectronics. Recently, superconductivity has been realized in graphene moiré heterostructures1–4; however, many of these structures are ...
