In a previous paper [Weiguo Yin, Phys. Rev. Res. 6, 013331 (2024)], the forbidden spontaneous phase transition in the one-dimensional Ising model was found to be approachable arbitrarily closely in decorated ladders by ultranarrow phase crossover (UNPC) at a given finite temperature T0 with the crossover width 2δT reduced exponentially, which resembles a genuine first-order transition with large latent heat.

Abstract Understanding charge motion in a background of interacting quantum spins is a fundamental problem in quantum many-body physics. The most extensively studied model for this problem is the so-called t−t′−t′′−J model, where the determination of the parameter t′ in the context of cuprate superconductors is challenging.
