High-temperature region on nickelates where superconductivity emerges/ then disappears, as pressure/ chemical doping is increased

"peaks at specific electron density, where magnetism/ superconductivity intertwine... extreme pressure tunes crystal lattice causing temperature at which becomes superconductor rises significantly before dropping off again, forming peak... at peak's edges superconductivity competed away by charge density waves... future: optimizing toward room-temperature, leading to lossless power grids, ultra-fast maglev trains, more powerful quantum computers that don't require expensive liquid helium cooling"
