Ferromagnetic half levitation of LK-99-like synthetic samples [PDF]
We successfully synthesized polycrystalline LK-99-like ceramic samples with a solid-state-sintering method. Powder X-ray diffraction shows that the main contents are Pb_10− x Cu_ x (PO_4)_6O and Cu_2S, consistent with recent reports (arXiv: 2307.12037 ...

Absence of Superconductivity in LK-99 at Ambient Conditions [PDF]
The report of the synthesis of modified lead apatite (LK-99), with evidence of superconductivity at more than boiling water temperature, has steered the scientific community.

Synthesis of possible room temperature superconductor LK-99: Pb9Cu(PO4)6O [PDF]
The quest for room temperature superconductors has been teasing scientists and physicists, since its inception in 1911 itself. Several assertions have already been made about room temperature superconductivity, but have never been verified or reproduced ...

Superionic Phase Transition of Copper(I) Sulfide and Its Implication for Purported Superconductivity of LK-99 [PDF]
Lee, Kim, and coworkers have recently claimed room-temperature and ambient-pressure superconductivity in a copper-doped lead apatite material named LK-99.

Two-qubit silicon quantum processor with operation fidelity exceeding 99% [PDF]
Silicon spin qubits satisfy the necessary criteria for quantum information processing. However, a demonstration of high-fidelity state preparation and readout combined with high-fidelity single- and two-qubit gates, all of which must be present for ...

Electronic structure and vibrational stability of copper-substituted lead apatite LK-99 [PDF]
Two recent preprints in the physics archive (arXiv) have called attention as they claim experimental evidence that a Cu-substituted apatite material (dubbed LK-99) exhibits superconductivity at room temperature and pressure. If this proves to be true, LK-
