Geometric phase signature of quantum criticality in the XY spin chain with multiple interaction

We investigate the quantum critical behavior in the XY spin chain with multiple interaction by means of geometric phase (GP). Near the critical point, the key ingredients of the quantum criticality are investigated carefully, and the results show that the GP is reliable to characterize the quantum c...

Summary:We investigate the quantum critical behavior in the XY spin chain with multiple interaction by means of geometric phase (GP). Near the critical point, the key ingredients of the quantum criticality are investigated carefully, and the results show that the GP is reliable to characterize the quantum critical behavior in such system and the multiple interaction can induce the redistribution of the criticality region.
