Sequential quantum phase transitions in $J_{1}$ - $J_{2}$ Heisenberg chains with integer spins ( $S > 1$ ): Quantized Berry phase and valence-bond solids

Shota Fubasami, Tomonari Mizoguchi, Yasuhiro Hatsugai

On the basis of a Berry-phase analysis, we study the ground state of the $J_{1}$ - $J_{2}$ Heisenberg chain for $S = 2, 3, 4$ . We find that changes of the Berry phase occur $S$ times for spi…
