Non-magnetic impurities in a strong-leg spin ladder

Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood...自旋S=½的反铁磁（Antiferromagnetic，缩写AF）自旋梯子是量子磁学领域中最为重要的模型之一。尽管其在(H,T)相图全域内的各项性质均可被认为已得到充分理解……
