摘要
我们发现，与 Majorana 填充约瑟夫森结阵列电容耦合的微波腔最低本征态中的 QED，由在系统参数有限域内出现的有效 模型描述。腔模式的强非谐性源于由单电子零模和超导岛间库珀对隧穿促进的电偶极相变。预测了有限温度下电磁场势的瞬子式蜿蜒。

备注
We withdraw this manuscript, because a more accurate calculation has shown that the mean-field value of the dipole moment of the Majorana-Josephson junction is reduced to zero due to zero-point fluctuations
