Swift"},{"name":"John L.

We argue that the flat band is an artifact of the functional's overestimation of the energy of the oxygen p states in the valence band. When using the HSE hybrid functional, the energy of the oxygen p states is reduced, and the copper-derived manifold splits into one fully occupied and one empty band. While these results do not rule out the possibility of superconductivity in doped LK-99, they do predict that stoichiometric $\\mathrm{Pb}_9\\mathrm{Cu}(\\mathrm{PO}_4)_6(\\mathrm{OH})_2$ is an insulator, not a superconductor. Furthermore, we have shown that future first-principles studies of these materials should employ hybrid functionals or other advanced methods to ensure that the oxygen-derived valence-band energies are correctly described.","source":"arXiv","year":2023,"language":"en","subjects":["cond-mat.supr-con","cond-mat.mtrl-sci","cond-mat.str-el"],"url":"https://arxiv.org/abs/2308.08458","pdf_url":"https://arxiv.org/pdf/2308.08458","is_open_access":true,"published_at":"2023-08-15T12:36:37Z","score":67},{"id":"arxiv_1809.08418","title":"Magnetic field induced charge order in cuprate superconductors: an explanation by spin-vortex-induced loop currents","authors":[{"name":"Daichi Manabe"},{"name":"Hiroyasu Koizumi"}],"abstract":"We present a possible explanation for a recently observed magnetic field induced charge order in cuprate superconductors (Edkins et al.~arXiv:1802.04673 [cond-mat.supr-con]). We argue that it arises from the reorganization of spin-vortex-induced loop current (SVILC) pattern due to supercurrent-flow caused by the magnetic field. The reorganization is from the most stable tiling of $4a times 6a$ spin-vortex quartets ($a$ is the lattice constant in the CuO$_2$ plane, and a spin-vortex quartet is stable of unit of spin-vortices that contains four holes, four spin-vortices, and four SVILCs) to that of $4a times 8a$ spin-vortex quartets. The consequence of this reorganization will lead to the enhancement of $8a$ charge order, and reduction of $6a$ charge order. The former is observed in the experiment, but the latter is not confirmed, so far. However, it may be confirmed if the experimental result is carefully reexamined.","source":"arXiv","year":2018,"language":"en","subjects":["cond-mat.supr-con"],"url":"https://arxiv.org/abs/1809.08418","pdf_url":"https://arxiv.org/pdf/1809.08418","is_open_access":true,"published_at":"2018-09-22T09:45:41Z","score":62},{"id":"arxiv_1205.6923","title":"Variation of Longitudinal Plasma Wavelength under Irradiation and Double Resonance in Coupled Josephson Junctions","authors":[{"name":"Yu.
