Weyl Josephson circuits

Year: 2021

Type: article

Abstract: 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 threedimensional (3D) Weyl Hamiltonian with broken inversion symmetry and in which topological phase transitions can be triggered in situ.We argue that currently available superconducting circuit technology allows experiments that probe topological properties inaccessible in condensed matter systems.
