Spontaneous Symmetry Breaking in Two-dimensional Long-range Heisenberg Model
Tianning Xiao, Dingyun Yao, Lode Polle +2
Algebraically decaying interactions can lead to nontrivial universality beyond short-range (SR) theories and spontaneous symmetry breaking in low-dimensional syst…

The Nonclassical Regime of the Two-dimensional Long-range XY Model: a Comprehensive Monte Carlo Study
Dingyun Yao, Tianning Xiao, Chao Zhang +2
The two-dimensional (2D) XY model plays a crucial role in statistical and condensed matter physics. With the introduction of long-range interactions, the system exhibits a richer s…

Asymptotic Freedom and Finite-size Scaling of Two-dimensional Classical Heisenberg Model
Dingyun Yao, Chao Zhang, Z. Y. Xie +2
The classical Heisenberg model is one of the most fundamental models in statistical and condensed matter physics. Extensive theoretical and numerical studies suggest that, in two d…
