In the modified Haldane model, antichiral edge states appear at the boundary of zigzag honeycomb nanoribbons. These flow oppositely at the boundary and the center of the ribbon. In this work, the authors show how to decorate the system boundary to control the edge modes’ current and spin polarization. They show how to form a three-terminal system where an unpolarized current splits into two fully spin-polarized ones.
