Unsupervised Discovery of Intermediate Phase Order in the Frustrated $J_1$-$J_2$ Heisenberg Model via Prometheus Framework
arXiv:2602.21468v5 Announce Type: replace-cross
Abstract: The spin-$1/2$ $J_1$-$J_2$ Heisenberg model on the square lattice exhibits a debated intermediate phase between N\’eel antiferromagnetic and stripe ordered regimes, with competing theories prop…
