研究了两层相互电容耦合的超小型约瑟夫森结中的量子相变。随着层间电容的增加，系统在零温度下表现出绝缘体到超导体的转变。结果表明，与具有类似耦合配置的一维阵列的情况不同，转变不能完全由粒子-空穴对来解释。
Quantum phase transitions in two layers of ultrasmall Josephson junctions, coupled capacitively with each other, are investigated. As the inter-layer capacitance is increased, the system at zero temperature is found to exhibit an insulator-to-superconductor transition. It is shown that, unlike in the case for one-dimensional arrays with a similar coupling configuration, the transition cannot be accounted for exclusively by particle-hole pairs.
