In condensed matter systems, the atoms, electrons or spins can sometimes arrange themselves in ways that result in unexpected properties but that cannot be detected by conventional experimental probes. Several historical and contemporary examples of such hidden orders are known and more are awaiting discovery, perhaps in the form of more complex composite, entangled or dynamical hidden orders.

隐藏，纠缠和共鸣的秩序

在凝聚态系统中，原子，电子或自旋有时会以某种方式排列自身，这些方式会导致无法预期的特性，但常规实验探针无法检测到这些特性。此类隐藏命令的一些历史和当代示例是已知的，并且有待进一步发现，可能以更复杂的复合，纠缠或动态隐藏命令的形式出现。
