论文摘要
我们介绍了Weyl Josephson电路:模拟Weyl带结构的小Josephson枢纽电路。我们首先制定了一种通用方法来设计电路,该电路类似于所需维度和对称性类别的Bloch Hamiltonians。然后,我们构建和分析了一个六接连接的设备,该设备产生一个3D Weyl Hamiltonian,其反转对称性损坏,并且可以触发拓扑相变,可以触发\ emph {原位}。我们认为,当前可用的超导电路技术允许在凝结物质系统中无法访问探测拓扑特性的实验。
We introduce Weyl Josephson circuits: small Josephson junction circuits that simulate Weyl band structures. We first formulate a general approach to design circuits that are analogous to Bloch Hamiltonians of a desired dimensionality and symmetry class. We then construct and analyze a six-junction device that produces a 3D Weyl Hamiltonian with broken inversion symmetry and in which topological phase transitions can be triggered \emph{in situ}. We argue that currently available superconducting circuit technology allows experiments that probe topological properties inaccessible in condensed matter systems.
