我们表明，平均场共振价键近似Baskaran，邹，和安德森在1987年提出的描述限制到边界的自旋布里渊区的无隙电荷对激发。这些电子对的存在解释了铜氧化物所有基本的反常电子性质，超导性是由于自旋超流的电荷拖曳而产生的。这种机制可能与其他非常规超导体有关。
We show that the mean-field resonating valence bond approximation proposed in 1987 by Baskaran, Zou, and Anderson describes gapless charge pair excitations confined to the boundaries of the spinon Brillouin zone. The existence of such pairs accounts for all the essential anomalous electronic properties of cuprates, with superconductivity arising due to the charge drag by the spinon superflow. This mechanism may be relevant to other unconventional superconductors.
