Abstract
We study the quantum spin pumping of an antiferromagnetic spin‐1/2 chain with competing exchange interactions. We show that spatially periodic potential modulated in space and time acts as a quantum spin pump. In our model system, an applied electric field causes a spin gap to its critical ground state by introducing bond‐alternation exchange interactions.
