Topological Identification of Spin-1/2 Two-Leg Ladder with Four-Spin Ring Exchange

I. Maruyama, T. Hirano, Y. Hatsugai

A spin-1/2 two-leg ladder with four-spin ring exchange is studied by quantized Berry phases, used as local order parameters. Reflecting local objects, non-trivial () Berry phase…
