Figure 1

A model system that demonstrates an anomaly in quantum phases. (a) This one-dimensional spin system with a finite number of sites N can be viewed as the sum of two topologies: a spin-circle with isotropic interaction among nearest-neighbor sites and a spin-line segment consisted of two sites with arbitrary coupling strength. (b) With increased or decreased bending, the coupling between the two ends of the system becomes stronger or weaker.
