摘要

Abstract
In recent years, spin-1/2 dimerized antiferromagnets have become
a remarkable subject since rich eld-induced quantum phases
can appear. In this work, we study second order quantum phase
transition caculated by this combined algorithm of the innite timeevolving
block decimation method and tensor renormalization group
approach. By applying an enough magnetic eld, a spin superuid
phase is observed. Moreover, a supersolid phase is also observed in
small regime of magnetic eld. We will show the full phase diagrams
in various weaker frustrating interlayer interaction.
