摘要: 通过建立纠缠态表象,给出了介观持久电流环的玻色子型相位算符与角动量算符,以实现介观持久电流环的角动量-相角量子化,并自然导出其本征能谱.最后引入角动量升降表象,发现电流环的角动量的增减对应着环中的电流增减.

Abstract: The entangled state representation was establish,in which the phase operator and the angular momentum operator have been applied, to realize the phase-angular momentum quantization of mesoscopic persistent current ring (MPCR) , and derive its energy spectrum. In addition,it was revealed that the ascending/lowering of angular momentum corresponds to the currents increase/decrease through angular momentum representation for the persistent current ring.

Key words: mesoscopic persistent current ring, entangled state, energy spectrum
