论文摘要
通过定期驾驶具有杂质的单个玻色粒约瑟夫森连接(BJJ),在系统的Fock空间中生成一个合成规场。在临界合成量规通量下,基态经历了量子相变,该量子过渡类似于在II类型超导体中发现的带有施加磁场的Meissner-Abrikosov-Qultex转变。证明了涉及BJJ玻色子之间有吸引力相互作用的第二个量子相变,可增强系统对Meissner-Abrikosov-Wortex涡流的敏感性。
By periodically driving a single bosonic Josephson junction (BJJ) with an impurity, a synthetic gauge field is generated in the Fock space of the system. At a critical synthetic gauge flux the ground state undergoes a quantum phase transition which is analogous to the Meissner-Abrikosov-vortex transition found in type-II superconductors with an applied magnetic field. A second quantum phase transition involving attractive interactions between the bosons of the BJJ is shown to enhance the sensitivity of the system to the Meissner-Abrikosov-vortex transition.
