Doping effects in a S = 1/2 spin ladder system near quantum criticality

Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel...自旋梯子（Spin ladders）是研究量子相变的优异模型系统，因其存在介于非磁性自旋单重态二聚体与奈尔（Néel）态之间的量子临界点而广受关注。
