| 英文摘要 | The recently discovered nickelate superconductors appear, at first glance, to be even more complicated multi-orbital systems than cuprates. To identify the simplest model describing the nickelates, we analyse the multi-orbital system and find that it is instead the nickelates which can be described by a one-band Hubbard model, albeit with an additional electron reservoir and only around the superconducting regime. Our calculations of the critical temperatureT(C)are in good agreement with experiment, and show that optimal doping is slightly below 20% Sr-doping. Even more promising than 3dnickelates are 4dpalladates. |
