Abstract: We have shown that the chiral shift in helicity of a quantized spinor, represented by the Berry phase, is only detectable in the presence of frustration. Hatsugai noted that the local topological order of the spin liquid is reflected in the quantized Berry phase represented by and. In the quantum transport of strongly correlated spin systems, the spin Berry phase is essential. Moreover, the chiral anomaly in the field theoretical aspect illustrates the net shift of spin chirality induced by this phase. Comparing the Berry phase with and without frustration is the aim of this study.
