具有Kasteleyn转变的二维自旋-冰模型的熵与磁化强度的函数关系
Entropy as a function of magnetization for a 2D spin-ice model exhibiting a Kasteleyn transition
摘要：
我们提出了一个组合的分析和数值研究的熵作为磁化的可定向的2D自旋冰模型，表现出Kasteleyn过渡的函数。我们使用的模型是众所周知的六顶点模型，但正如我们所展示的，我们的代表性，它是更方便的构造近似表达式的熵在固定磁化。我们还讨论了进一步工作的方向，包括变形我们的模型到一个展示量子Kasteleyn过渡的可能性。
英文摘要：
We present a combined analytical and numerical study of the entropy as a function of magnetization for an orientable 2D spin-ice model that exhibits a Kasteleyn transition. The model that we use is related to the well known six-vertex model but, as we show, our representation of it is more convenient for constructing approximate expressions for the entropy at fixed magnetization. We also discuss directions for further work, including the possibility of deforming our model into one exhibiting a quantum Kasteleyn transition.
