拓扑玻璃态

Topological glass states

Tai-Kai Ng, Yi Zhou, Lei-Han Tang

摘要:

在最近的讨论拓扑秩序和拓扑相变在量子系统中,我们重新审查的情况下,导致出现的拓扑玻璃在某些经典的晶格自旋模型。局部成键对低能态施加约束,低能态将自身组织成拓扑上不同的类,这些类破坏遍历性,但不像通常的朗道相变理论中那样破坏任何明显的对称性。使用两个经典的类伊辛模型证明了这样的拓扑玻璃的各种性质。

英文摘要:

In connection with recent discussion of topological order and topological phase transitions in quantum systems, we reexamine circumstances that lead to the appearance of a topological glass in certain classical lattice spin models. Local bonding enforces constraints on low energy states which organize themselves into topologically distinct classes that break ergodicity but not any apparent symmetry as in the usual Landau theory of phase transitions. Various properties of such a topological glass are demonstrated using two classical Ising-like models.
