论文摘要
在二维方形冰中恢复地面堕落性是几何挫败感的重大挑战，具有深远的基本意义，例如实现顶点模型，并了解降低维度的效果。我们将实验，理论和数值模拟结合在一起，以证明剪切的方形胶体冰部分恢复了地面堕落，以获得广泛的田间强度和晶格剪切角。我们的方法开辟了一条途径，以基于剪切的磁性晶格在各种柔软和凝结的系统系统中设计出一种新颖的沮丧的微型和纳米结构。
Recovery of ground-state degeneracy in two-dimensional square ice is a significant challenge in the field of geometric frustration with far-reaching fundamental implications, such as realization of vertex models and understanding the effect of dimensionality reduction. We combine experiments, theory, and numerical simulations to demonstrate that sheared square colloidal ice partially recovers the ground-state degeneracy for a wide range of field strengths and lattice shear angles. Our method opens an avenue to engineer a novel class of frustrated micro- and nano-structures based on sheared magnetic lattices in a wide range of soft- and condensed-matter systems.
