量子自旋链中的自发宇称破坏
Spontaneous Parity Violation in a Quantum Spin Chain
摘要：
我们报道了一个包含最近邻相互作用的自旋哈密顿量的基态宇称的自发击穿。这发生在一维模型中，其中自旋在QCD的规范场表示（SU（3）的八维伴随表示）下变换。基态自发违反宇称，是双重简并的。此外，该模型具有一个非零的拓扑弦序参量，我们解释了解析。
英文摘要：
We report on a spontaneous breakdown of parity in the ground state of a spin Hamiltonian involving nearest-neighbor interactions. This occurs for a one-dimensional model where spins transform under the gauge field representation of QCD, the eight-dimensional adjoint representation of SU(3). The ground state spontaneously violates parity and is two-fold degenerate. In addition, the model possesses a non-vanishing topological string order parameter which we explicate analytically.
