Magnetic and electric order in the spin-1/2 XX model with three-spin interactions

Magnetic and electric order in the spin-1/2 XX model with three-spin interactions

We study the spin-1/2 XX model in the presence of three-spin interactions of the XZX+YZY and XZY-YZX types. We solve the problem exactly and show that there is both finite magnetization and electric polarization for low non-zero strengths of the three-spin interactions.
