论文摘要
我们将简并平方自旋描述为磁性单极的集合，该集合通过出现的熵场耦合，该场均包含了基础自旋真空的效果。我们计算其有效的自由能，熵相互作用，相关性，筛选和与实验性相一致的结构因子。与Pyrochlore ICE中不同，真实和熵相互作用之间的尺寸不匹配导致捏点处的奇异性较弱，并且长距离的代数相关性。但是，这种代数筛选可以通过伪屏幕制度掩盖。
We describe degenerate square spin as an ensemble of magnetic monopoles coupled via an emergent entropic field that subsumes the effect of the underlying spin vacuum. We compute their effective free energy, entropic interaction, correlations, screening, and structure factors that coincide with the experimental ones. Unlike in pyrochlore ices, a dimensional mismatch between real and entropic interactions leads to weak singularities at the pinch points and algebraic correlations at long distance. This algebraic screening can be, however, camouflaged by a pseudo-screening regime.
