论文摘要
我们提出了一项在四个维度上的经典海森堡模型的高精度蒙特卡洛研究,表明在断裂的对称相中,IT支持拓扑,单极样激发,其特性证实了先前在量子场理论中得出的分析预测。我们讨论了这些发现的相关性及其在凝结物理学中的可能实验应用。
We present a high-precision Monte Carlo study of the classical Heisenberg model in four dimensions, showing that in the broken-symmetry phase it supports topological, monopole-like excitations, whose properties confirm previous analytical predictions derived in quantum field theory. We discuss the relevance of these findings and their possible experimental applications in condensed-matter physics.
