Symmetry-protected topological phases and competing orders in a spin-1/2 XXZ ladder with a four-spin interaction

Takuhiro Ogino, Shunsuke Furukawa, Ryui Kaneko +2

We study a spin-1/2 XXZ model with a four-spin interaction on a two-leg ladder. By means of effective field theory and matrix product state calculations, we obtain rich ground-stat…
