Half-ice, half-fire-driven ultranarrow phase crossover in one-dimensional decorated -state Potts ferrimagnets: An AI-co-led exploration
Weiguo Yin
OpenAI's reasoning model o3-mini-high was used to carry out an exact analytic study of one-dimensional ferrimagnetic site- and bond-decorated -state Potts models. We demonstrate…

Site-decorated model for unconventional frustrated magnets: Ultranarrow phase crossover and two-dimensional spin reversal transition
Weiguo Yin
The site-decorated Ising model is introduced to advance the understanding and experimental realization of the recently discovered one-dimensional (1D) finite-temperature ultranarro…

Metamagnetic Transition in Low-Dimensional Site-Decorated Quantum Heisenberg Ferrimagnets
Weiguo Yin, A. M. Tsvelik
The prohibition of finite-temperature phase transition in one-dimensional (1D) Ising models and 1D/2D quantum Heisenberg models with short-range interactions fundamentally constrai…
