讨论了颗粒超导体中可能存在的轨道玻璃态。轨道玻璃（新的拓扑玻璃）与约瑟夫森结的特殊环的存在有关，这种特殊环具有正、负约瑟夫森耦合。当环上有奇数个负耦合时，就会产生一个自发的轨道矩。与任意子超导类似，具有轨道矩的新态的特征是基本对称性破缺（C和P）
We discuss a state of an orbital glass which may exist in granular superconductors. The orbital glass (new topological glass) is related to the existence of the special loops of Josephson junctions with positive and negative Josephson couplings. With an odd number of negative couplings on the loop, a spontaneous orbital moment is created. Similar to anyon superconductivity, the new state with orbital moments is characterized by broken fundamental symmetries (C and P)
