标题： Weyl Josephson Circuits

摘要： 我们引入了Weyl约瑟夫森电路：模拟Weyl能带结构的小型约瑟夫森结电路。我们首先制定了一种通用方法来设计与所需维度和对称类的布洛赫哈密顿量相对应的电路。然后，我们构建并分析了一个由六个约瑟夫森结组成的器件，该器件生成具有破缺反演对称性的三维Weyl哈密顿量，并且可以通过此设置触发拓扑相变\emph{原位}。我们认为，目前可用的超导电路技术允许实验探测凝聚态系统中无法触及的拓扑性质。 显示英文摘要

摘要： 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.
