Absence of local conserved charges of the Fredkin spin chain and its truncated versions
Wen-Ming Fan, Kun Hao, Yang-Yang Chen +3
Conservation laws serve as the hallmark of integrability. The absence of conserved charges typically implies that the model is nonintegrable. The recently proposed Fredkin spin cha…
