Researchers Simulate Fierce Rivalry Between Superconductivity & Stripes

Quantum ZeitgeistOctober 25, 20264 min read

At just one eighth doping, simulations now resolve energetic differences previously blurred by computational limits, revealing competing electronic states separated by mere milli-t. This precision, achieved on lattices up to 1024 sites, demonstrates that hole-doped materials don’t necessarily favour *one* ground state over another. Instead, superconductivity and various striped orders exist in surprising balance, demanding a reassessment of high-temperature superconductor theory.

Determining the ground state of the hole-doped Hubbard model, a key to understanding high-temperature superconductivity, has been hampered by uncertainty in computational methods. Ao Chen, Johnnie Gray, Si-Jing Du and Garnet Kin-Lic Chan achieved unprecedented accuracy using advanced simulations on lattices up to 1024 sites; these calculations reach a precision of a few milli-t. Simulations have revealed a surprising level of competition between different electronic states within materials thought to hold the key to high-temperature superconductivity;…
